Sierra High Route

The Idea:

The Sierra High Route has intrigued me ever since I heard of the fabled 195 mile trek almost a decade ago. The SHR  parallels the John Muir Trail but about 60% of it is off-trail, opting for higher passes instead of diving down into the forested canyons. The route visits some of the most wild and remote corners of the range and entails some arduous terrain, including much talus hoping, but also plenty of the friendly granite terrain and alpine meadows that make cross country travel in the Sierra Nevada high country so feasible. In all the SHR gains about 60,000 feet of elevation while traversing through 33 passes and most of that elevation gain comes off-trail. Steve Roper designed the SHR and provides great detail about the route in his book, Sierra High Route: Traversing Timberline Country, first published in 1982 and now in its second edition available on Amazon (see special note at the bottom of this post on the perils of using “free” maps). Roper divided the SHR into sections so trekkers can tackle sections at a time. It appears this mode of completing portions the SHR has become increasingly popular while thru hiking the entire route in one trip is still a rather rare occurrence. Anecdotally, only about a dozen folks thru hike the complete SHR each year. The SHR also does not lend itself to supported efforts. For one, it’s even more remote than the JMT posing extra difficult logistical complexities. Second, it just doesn’t comport with the ethos of the route. The SHR is intended to be a conduit where one gets off the JMT wilderness freeway and acquires a more intimate experience with the range in remote and wild places. An unsupported SHR feels like the only way to do the SHR in my opinion.

My Philosophy: 

Through my various adventures over the years in and around the SHR I’ve accumulated a wealth of knowledge and finally felt familiar enough with the terrain and the new (for me) complexities of ultralight, unsupported multi-day travel to attempt the route last summer. However, I had a vision for how I wanted my trek to look. Much more than any fast time, I wanted clear, crisp days with excellent visibility. Above anything else, I wanted to experience and enjoy the scenery when it was at its finest, and not dulled by wildfire smoke or obscured by afternoon thunderstorms.  When the time came to set out for the route in the summer of 2015, the historic Rough Fire was poised to explode in Kings Canyon and become the largest fire ever in the Southern Sierra. I held strong to my vision and opted not to join Brian Lucido on his SHR trip which included thick afternoon smoke during the first couple days and cars trapped at Roads End for weeks. Unfortunately, the Rough Fire continued to burn into autumn and the starting point of the SHR at Kings Canyon remained closed through spring 2016. I would have to be patient and wait until summer 2016 to make my SHR vision come to fruition.

Fast forward to spring 2016 and the SHR continued to intrigue me as much as ever. After a few successful overnight trips honing in on my gear and nutrition plan I was ready once again. After waiting patiently, the weather pattern I had envisioned appeared. There would be no chance of afternoon thunderstorms, and most importantly, there would be no wildfire smoke to reduce visibility. I had done the preparation and now it was time to enjoy the route. 

My Story: 

Focusing on the drama or giving a play-by-play is not my writing style so I wont attempt to do either with this write-up. Instead I hope to focus on aspects that I think are interesting and hopefully useful. For a detailed description of the route, it’s essentially a requirement that one purchases Steve Roper’s book which does a fantastic job describing the SHR in detail including an excellent account of the history of exploration in the Sierra Nevada.

My preparation for the trip entailed many weekends in the Sierra Nevada climbing peaks and gaining acclimation. I did a few overnight trips to become familiar with my gear setup and nutrition needs. Many of the outings included climbing peaks with more technical scrambling and more rigorous off-trail travel as compared with the SHR. Thus, when I was doing the SHR, I often felt like the route was less taxing than my normal weekend routes. 

Luckily there was very little drama on my trip, and that was by design. I’d like to think that my meticulous, some might say excessive, preparation is responsible for eliminating most of the drama. However, my trip was not without problems as there are almost always glitches on multi-day trips for which one must adapt. At the end of Day 1 I turned my ankle and the zipper on my sleeping bag broke. The ankle turn was only a grade 1 sprain and my walk down from Dusy Basin to LeConte Canyon the morning of day 2 was painful, but without swelling or discoloration I knew that it would ultimately be ok. Once I started ascending toward Muir Pass and the pressure was taken off the impacted ligament I became more confident that this ankle turn would not impact the trip. This close call may have even been a blessing in disguise proving to me that I was one careless step away from having to abandon the route. If I wanted to see all of the beautiful scenery that the SHR has to offer and complete my multi-year vision, I would need to make sure that I did not injure myself! From that moment on, I maintained a laser focus when rock hoping on the often unstable talus rocks. The broken sleeping bag zipper was something that I had to adjust to. I wrapped my bivy sack tighter and made my sleeping bag into more of a quilt to negate the drafting of cold air. It was not ideal but it would make do. That just about sums up the drama! 


A big part of the puzzle of undertaking something like the SHR fast is dialing in on nutrition. One must carry enough calories, and the right kind of calories, to negotiate the dozens of passes and arduous off-trail terrain. My food for the trip would be a mix of high calorie to weight ratio solid foods combined with more traditional energy gels and chews for endurance activities. I would start with ~20,000 calories which equates to around 9.5 pounds.

Dinner and breakfast:

  • I relied heavily on a granola mix including pumpkin seeds, pecans and cashews. This amounted to 5000 calories, or a quarter of all calories I carried.
  • Sunflower seed butter
  • Norwegian flat bread, a seed-filled, dense cracker
  • First Endurance Ultragen for a recovery drink each night

During the day:

  • Picky bars, Epic bars, energy waffles, Gu gels and Clif shot blocks. This mix of energy foods was easy to consume on the go and would provide the necessary carbs and fat to power me throughout the long days.


  • Nuun and Gu Hydration Tabs
  • Gu Electrolyte Capsules
  • SaltStick

Gear Considerations and Night Travel: 

In particular for a fast attempt at the SHR (vs. multi-day efforts on trails), one must carry the appropriate gear to enable some rest and relaxation at night. First, a lot of the SHR is not efficiently navigable in the dark so there is some built in down time during the “cold hours.” On many sections traveling at night would result in more energy wasted than progress made. Even more importantly for me, I was there to enjoy the scenery first and foremost and I wouldn’t be able to do that in the dark. I didn’t want to miss ANY of the scenery! What would be the point passing through some of my favorite parts essentially blindfolded? Thus, I would reserve any night travel for sections of mundane trail.

Second, the SHR mostly travels above 10,000 feet so even in the warmest periods of the summer it gets rather chilly at night, often into the 30s and even below freezing. This fact, coupled with the tendency for my core temperature to plummet immediately after stopping at the conclusion of a long day, meant that carrying the appropriate gear to get my core temperature back up was critical. I also new that the crisp and pleasantly cool (below average) afternoon temps that would be to my advantage while moving during the day would also produce colder nights. Thus, I needed to prepare for overnight temps below freezing. Indeed, I would find frost next to my bivy on most mornings.

Third, the arduous off-trail nature of the SHR does not lend itself to efficient round-the-clock travel. Too much strain on the muscles without appropriate recovery in the early stages, both in terms of duration and intensity, could spell extreme difficultly on the many difficult passes that appear in the later stages of the route. Much more than any on-trail adventure like the JMT, one must be strategic when and how to up the intensity. Instead I took a more balanced approach focusing on sustained, moderate intensity movement. The pace I attempted to establish was by no means pedestrian, but it was also not at a level that I knew could become problematic to maintain, and in the worst case, potentially result in a blow up (exhaustion, muscle cramps, etc.). I also planned to build in a considerable amount of rest in the early stages of the trip to ensure that my legs would remain reasonably fresh to enable me to maintain the same pace into the later stages of the route. If I felt good towards the end I would be able to up the intensity and put in some longer days. After all, I always prefer to finish strong!

My sleep setup included the following:

  • Mountain Hardwear Mountain Speed sleeping bag: overall I was pleased with the performance of the bag but the zipper is just awful: always getting caught and, as I found, liable to simple break in the field!
  • Mountain Hardwear Ghost Whisperer hooded down jacket: I love this jacket. It kept me warm and the hood over my head was key to getting my core temperature back up.
  • Ultimate Direction Marathon Jacket: I used the marathon jacket extensively during the trip and for only 3.3 ounces it did an amazing job keeping me warm. In the evenings I would put it on top of my shirt and in the sleeping bag I would put it on top of my down jacket to provide that extra warmth. (note: if any chance of rain was in the forecast I would have replaced the UD Marathon Shell with the UD Ultra Jacket, which comes in at only ~2 ounces heavier but provides much more protection from wind and rain).
  • SOL Escape Lite Bivvy: The purpose of the bivy was to give me another 10 degree temperature rating on my sleeping bag. Without this bivvy I would have almost certainly been cold most nights. With the bivy I was comfortably warm.
  • Thermarest Neoair Xlite: The gold standard for light inflatable mattresses. Perhaps just as important as sleep was giving my muscles a few hours to relax and recover for the next day of movement. Sleeping on hard, cold ground would make that difficult to accomplish. The Neoair weighs about as much as a non-inflatable pad, packs down smaller and would give me a cushy surface to rest on any surface, including rock slabs.
  • Gossamer gear polycro groundsheet: This sheet of plastic doesn’t look like much, but it’s remarkably strong and extremely important to protect the inflatable mattress and otherwise keep gear off the ground surface and clean.
  • Liner gloves: These were useful on the cold mornings to keep my fingers warm.
  • Ultimate Direction Midcap: coming in at only 0.5 ounces, it seems like a no-brainer to carry this little beanie. I wore this hat every night and every morning. It kept my head toasty. Like my mom always says, staying warm starts first with the head!

Other gear included the following:

  • Black Diamond Distance Z-Poles: These poles are extremely versatile and were up to the task of the rugged SHR. I was able to easily pack them away when I did not need them and the tougher aluminim build (vs the lighter carbon fiber ultra distance) was worth the extra weight. The ultra distance pole is not really designed for off-trail travel and a broken pole is just extra weight. The distance pole performed well.
  • Black Diamond SPOT headlamp 2016: This headlamp was lightweight and provided more than enough light for my few hours of use during the night.
  • Hydrapak Ultraflask XL 20 oz: This large soft bottle fit perfectly into the front pocket of my Ultimate Direction 30 Fastpack. The tube and bite valve meant only needed to turn my head to get a sip. Unlike a water reservoir, the Ultraflask was super easy to take out and refill.
  • Water bottle: I wasn’t ready to rely on a soft bottle entirely in case it sprung a leak so I brought a hard water bottle. It turns out the soft bottle held up fine and 95% of the water I drunk was from the Hydrapak Ultraflask. I basically only used the water bottle for mixing recovery powder.
  • Anker 10000 mAh portable charger: Used for recharging electronics including my Suunto Ambit 3 Peak watch and iPhone. This was more than enough charging capacity for my needs.
  • iPhone SE: Used for photography and navigation as necessary (with GAIA GPS App downloaded)
  • SPOT Receiver: The SPOT custom and OK buttons worked fine when engaged but I was quite disappointed with the performance of the tracking feature on this trip. There were a couple erroneous tracks and sometimes there was hours between tracks even though I set it to fix every 30 minutes. I obviously did not know about this shortcoming when I was out there which is even more frustrating. This failure is a little bit of a head scratcher: my iPhone can triangulate GPS to within 16 ft in a matter of seconds but the SPOT can be miles off or not even obtain a fix for hours at a time. The technology is obviously there but SPOT remains spotty…
  • Miscellaneous items: sunscreen, lip balm, insect repellent, small first aid kit, blister kit, toothbrush, toothpaste, etc.

SHR gear

So how would I carry all this food and gear comfortably?

  • Ultimate Direction Fastpack 30: The Fastpack 30 has plenty of space (and more) to carry all my food and gear for at least 5 nights. The integrated vest structure allows for comfortable transport and the numerous front pockets provide for easy access to items during the day including the Hydrapak Ultraflask XL, energy food, sunscreen, chapstick, iphone, SPOT receiver, etc.  While all my gear fit into the Fastpack 20, I preferred the Fastpack 30 since it has a foam back panel that provided me some structure to comfortably carry the load, which was around 17 pounds at the beginning of the trip. For lighter loads less than 14 pounds I would likely use the Fastpack 20.

And now, for the perhaps the most important piece of gear: footwear!

  • La Sportiva Akasha: The sticky, rugged outsole provided the traction I needed on slabs and talus while the cushioning gave my feet the comfort they needed to keep moving without any pains for the entire day. The roomy fit also kept blisters to a minimum and any shoe that can survive the rigors of the SHR is a winner!
  • La  Sportiva Long Distance Sock: A new product for La Sportiva this year, these socks were extremely comfortable and were up to the task of protecting my feet and keeping blisters to a minimum.
  • Injinji Compression Toesocks: Provide a ton of compression to help reduce muscle soreness. My calves in particular are susceptible to becoming tight during long days of intense activity and these socks were able to provide the level of compression that would alleviate tightness.


My plan for the SHR was loose and flexible. I would basically keep moving during the daylight hours and rest during the night. I had no specific destination to reach each day, only to keep moving until ~8 pm when I would find a suitable place to rest overnight. For the reasons described above, I knew that rest would be critical and I did not want to miss any highlights by bumbling around at night. When my energy levels during the day lowered, I would tell myself that it’s all about movement. If I kept moving as much as possible during the day, even at a pace that felt sluggish, I would still make substantial progress by the end of the day. The periods of low energy often happened during the heat of the day and made me thankful that I picked a relatively cool weather pattern to do the SHR (I don’t like heat). Thankfully, these periods of low energy would be relatively short since the temps would cool quickly in late afternoon with a breeze and I was diligent about eating food and drinking water with electrolytes. My goal was to smooth out the highs and lows that are inevitable on multi-day efforts and I feel like I was effective in execution.

Sub 5 Days: 

My initial analysis (even before last summer) was that it would be feasible for me to complete the SHR in under 6 days while still enjoying the scenery. Thus, heading into my attempt of the route I figured a finish of around 5.5 days was most likely. I was on track for exactly this type of finish as I came into Reds Meadow and I was actually assuming it would be a 5.5 day finish until the afternoon of day 4 around North Glacier Pass. At this point a light bulb went off in my head. I knew that if I could reach the north side of Blue Lake Pass I could potentially finish in under 5 days. This would require me to complete a difficult off-trail portion before sunset, but once completed, I would be able to cover some distance on the Isberg Pass and Rafferty Creek Trails in the dark. This would set me up for completing the last section of rugged off-trail travel north of Tuolumne Meadows during the daylight of day 5 and ultimately a sub 5 day finish. I was more than OK to cover some miles along the mundane trails at night since they tend to be hot and dusty during the day and there is virtually no scenery to enjoy along them. It seemed like a plan and the seed was planted so I set off around Lake Catherine with renewed vigor. The scenery from North Glacier Pass to Twin Island Lakes is astonishingly wild and rugged – some of the best on the entire route – and just the type of awe-inspiring beauty to get me super excited. I was grateful for the opportunity to be at this spot on such a beautiful day and enjoying every second. For the next few hours I would seek to reach Blue Lake Pass before sunset, inspired and motivated by my surroundings as evening light took hold of the land. I ultimately made Blue Lake Pass well before sunset and traversed the beautiful meadowy benches beneath Foerster Peak depositing me on the Isberg Pass Trail before nightfall.

From this point I would need to do about a dozen trail miles to set me up for a sub five day finish including the steep climb up Vogelsang Pass. I stopped for dinner at the Lyell Fork of the Merced River and then took a second break at Florence Creek to gather myself for a sustained effort up the steep switchbacks to Vogelsang Pass. I was soon over the pass and descending toward Vogelsang Lake. At this point I had a decision to make: keep going through the night or stop to rest for a few hours. If this were an all-trail effort I would have more strongly considered going through the night since I continued to feel good. However, I remembered Brian Robinson mentioning that the last few passes along the SHR were some of the hardest on the route. I knew that the prudent decision was to give my legs some rest in advance of these tough climbs and consume some more calories. I stopped at Vogelsang Lake and rested on a granite bench for a few hours. When I woke up I knew that I had made a good decision as my legs felt light again and I was able to run much of the way from Vogelsang Lake to Tuolumne Meadows. At this point I knew that I would have enough time to negotiate the arduous off-trail section from Great Sierra Mine to Horse Creek Pass entirely in the daylight hours and ensure a sub 5 finish. In fact only the last 2 miles of the SHR are on true maintained trail where running is feasible and I was happy to reach this section with plenty of daylight to spare.

The Finish: 

I arrived at Twin Lakes at 8 pm, 4 days, 16 hours and 45 minutes after beginning at Roads End in Kings Canyon. I was obviously tired, but not destroyed. My physical and mental spirits were in remarkably good shape. It appears the worst things that came out of the trip were burned lips (note:you can never use enough lip balm) and tight shoulder muscles.  In fact, I had a lot more soreness and mental exhaustion after the JMT FKT a couple years ago. I’m assuming this is due to the fact that the majority of the SHR was fast hiking vs. running and much less night travel compared to the JMT, which can be very taxing mentally and physically. Or perhaps I’ve learned a thing or two about multi-day efforts? My time happens to be a new Fastest Known Time, of which I’m grateful to have obtained. However, I’d be just as a satisfied with my experience had it not been an FKT as I was able to accomplish my top priority of enjoying the stunning scenery even more than I could have ever imagined. I realize that I am lucky to be in an era where I can proceed with my style of enjoyment and photography while still also achieving a benchmark time and redefining what is possible in terms of efficiency for a route like the SHR.


The Sierra High Route is a highlight real with numerous favorite spots along the way. One of the great advantages of multi-day travel is the ability to see sunrise and sunset at many of these remote spots when the “Range of Light” comes to life. Here are some of my favorite sections:

  1. Windy Ridge and Gray Pass: The view overlooking lake 10236 and the Middle Fork Kings Canyon is astonishing. It’s one of the great views of the high Sierra. In the past I’ve visited Windy Point which is a very worthwhile diversion.
  2. Marion Lake and Lake Basin: This stunningly blue body of water is tucked in underneath the granite cliffs of the Cirque Crest and Marion Peak. Above Marion lake lies several large bodies of water in Lake Basin that are equally beautiful. With no maintained trails entering the basin one can find solitude among natrual splendor.
  3. Palisade Basin: The Palisades are the most rugged and alpine subrange within the entire Sierra Nevada. The SHR passes immediately underneath these monolithic peaks crossing over rocky passes, green meadows and lovely lakes. I was able to see evening light as I passed through Palisade Basin on the way to Knapsack Pass on Day 1.
  4. Evolution Basin: For both the SHR and the JMT, the Evolution Basin is a highlight. Everything from Wanda Lake down to Evolution Lake is marvelous and some of the most classic Sierra scenery available.
  5. Bear Basin: Bear Basin is among my favorite spots in the entire Sierra Nevada. In particular, Ursa Lake and White Bear Lake are particularly stunning. Both lakes feature the rugged Seven Gables and Gemini peaks towering above their rocky shorelines. It was a treat to pass through Bear Basin during sunrise on Day 3.
  6. Upper Mills Lake: A pristine lake situated at the foot of the north face of Mount Gabb, the highest peak in the region. The lake is surrounded by an amphitheater of cliffs and is one of the more rugged and wild spots on the route.
  7. Cotton Lake and Izaak Walton Lake: Cotton Lake sits on a white granite bench which contrasts marvelously with the reddish rock of Red Slate Mountain and Red and White Mountain at the headwaters of Fish Creek. Izaak Walton Lake is situated among steep granite slabs tucked in beneath Mont Izaak Walton.
  8. The Minarets: Always a favorite, the trio of lakes beneath the striking Minarets are tough to beat. Each of the lakes – Minaret, Cecile and Iceberg – are amazing and I simply can’t rate one above the other. It’s all amazing and always a pleasure to pass by them and gaze in awe at Minaret spires towering above.
  9. North Fork San Joaquin Headwaters: The entire stretch of the SHR between North Glacier Pass and Blue Lake Pass is features some of the most rugged and wild terrain on the route. This is a land of cliffs, waterfalls and remote lakes. The beauty is austere and surreal and I love it!
  10. Conness Lakes: Set between Mount Conness and North Peak are a string of magical lakes, each with a different tinge of glacial sediment resulting in a range of colors from blue to bright turquoise. The SHR descends a lovely granite ramp from the East Ridge of Mount Conness down to these lakes providing a swell view of these lakes for the entire duration of the descent.

Thoughts on Speed: 

It so happens that the Sierra Nevada is my “home range” and I have spent a considerable amount of time in and around the Sierra High Route. I have climbed most of the local peaks, rested in countless meadows, and swam in many lakes. I am deeply familiar with this country and enjoy the flow of moving fast through this familiar terrain while also taking time to stop and smell the flowers. On my SHR journey, or any trip to the high Sierra for that matter, I do not feel as if I have “bagged” or “tagged” or “crushed” anything. These terms imply that I have somehow conquered the mountains but instead it’s the mountains that have given me everything on my visits to the high Sierra – the inspiration, the motivation and the memories that will last a lifetime. I want these mountains to remain wild forever. There are so few truly wild places remaining in the world, particularly in a populous state like California, where one can find nature in its purest and unfettered form. I am grateful for the opportunity to visit these places that humans will hopefully never “conquer.”

Especially for those who do not get to enjoy this tremendous mountain country on a weekly basis like I do, it is almost a shame to approach the SHR with a singular focus on speed. It’s simply too beautiful with too many opportunities for exploration. In fact, Roper devotes a section of each chapter to local peaks and strongly encourages the SHR traveler to take some (or many) of these tangents. By climbing the peaks and wandering the surroundings one comes away with an even greater appreciation of the Sierra and a greater sense of satisfaction.Through my many travels in the Sierra, I can say with certainty that the precise SHR route is just the beginning and a facilitator of these opportunities and experiences. I highly recommend that one adopts this ethos when planning a trip of the SHR.

With the SHR journey now complete I can say that I am now comfortable with multi-day unsupported efforts and I look forward to doing more of these types of adventures in the future. I have improved my ability to do consecutive long days in the mountains. I know how my body reacts on multi-day efforts, I can recognize the first signs of fatigue, and I can better gauge what type of nutrition I need to keep me going with a sustained effort day in and day out. All of these lessons will surely help me continue to explore the mountains in new ways.


My unsupported journey of the SHR would not be possible without the help of my good friend Will Gotthardt who generously offered his time to help drive me to the start at Roads End in Kings Canyon and pick me up at the finish at Twin Lakes near Bridgeport. Will always puts me at ease before events and has always believed in me so having him there at the start was invaluable. The car shuttle for the SHR is among the longest of all point-to-points and Will made it super easy on my end. Also special thanks goes to my partner girlfriend, Erica Namba, who endured days of me talking about various minutia regarding the route, gear and nutrition selection while providing valuable input on all of the above. She’s also soon to become a physical therapist and provided me with hours of therapy to keep me healthy. A special thanks goes to previous SHR thru-hikers Brian Robinson, Buzz Burrell, Andrew Skurka and Brian Lucido who generously imparted their knowledge and experiences of the route, either publicly on the internet or through direct communication. Finally, thanks to my gracious sponsors La Sportiva and Ultimate Direction. La Sportiva has been supporting my adventures for nearly a decade and their footwear continues to lead the pack when it comes to adventure running! Ultimate Direction makes the best hydration systems, hands down. The immensely successful Signature Series basically invented the running vest category and the Fastpack 20/30 are doing the same for multi-day adventures.

Special Note on Inaccurate Free Maps:

If you’re interested in doing all or part of the SHR, do NOT use the free maps on – do NOT use the overview maps, do NOT use the topo series, and (most importantly) do NOT use the GPX ( The line is neither accurate nor efficient; there are at least a dozen errors that obviously deviate from Roper’s description and a few of them are major deviations that will lead you astray and/or not complete the route as Roper described and intended. This information is so bad it’s actually a disservice to those interested in the SHR and there should be a bold disclaimer or, better yet, it should be taken off the internet. These maps show up high in any internet search for the Sierra High Route. I quickly realized they were basically garbage and I did not use them at all in my planning for the SHR.

Trinity Alps High Route Part III: Wedding Cake, Mount Hilton & Boulder Lakes

The third and final part of series of posts  on a two day fastpack of the Trinity Alps High Route covers the section from Thompson Peak to the trailhead at Canyon Creek inclduing Wedding Cake, Mount Hilton and Boulder Creek Lakes. This portion of the Trinity Alps High Route was previously covered in the Trinity Alps Traverse report from 2013 and that trip served as inspiration for the Trinity Alps High Route this year. Many additional photos can be found on the 2013 post with different lighting since this section was done in reverse. The preceding two posts were as follows:

From the summit of Thompson Peak descend the sandy southwest slopes and traverse granite benches to the short class 3 climb up a chute to the summit of Wedding Cake, which in my opinion has the best birds eye view of the Canyon Creek Lakes. After descending Wedding Cake traverse on the west side of the ridge until the crest can be easily crossed to the east side. At this point, an awesome 2+ mile “granite highway” section commences. This stretch is stunning with rugged unnamed peaks and spires towering above and sweeping views of the pristine granite slopes dropping off to the Canyon Creek Lakes below. The smooth white granite is interspersed with grassy meadow benches, krummholz and small cascading streams making for a delightful setting.

If headed for Mount Hilton, at the end of this marvelous stretch of granite slabs ascend to a high shoulder on the first of two sub-ridges that need to be crossed to access the Mount Hilton scramble. Once over this shoulder enter a smaller drainage with more talus than granite, but excellent views of the precipitous northeast buttress of Mount Hilton. After traversing through this cirque a convenient ramp can be used to pass the second sub-ridge and deposit one immediately beneath Mount Hilton (those skipping Mount Hilton could simply traverse below this sub-ridge and directly down to Boulder Creek Lakes). This ramp looks somewhat difficult from afar but in reality it’s a class 2 walk-up providing surprisingly easy passage through this barrier that would otherwise involve some tricky climbing. Once over the ridge, ascend steep alpine slopes to the foot of the final class 3 scramble portion up Mount Hilton. The summit provides an amazing vista of the surrounding mountains and an excellent overview of the Trinity Alps High Route. In particular, Sawtooth Mountain sports a particularly impressive profile across the Canyon Creek drainage. From the summit of Mount Hilton to Boulder Creek Lakes is a long and steep descent of over 3,000 feet down to the Boulder Creek Lakes. The upper part of this descent is fairly straightforward on rocks and gravel transitioning to sections of granite slabs in the middle. The lower portion of the descent requires some micro-navigating through some cliff bands and thick brush. Towards the bottom a creek bed may be used in later season to avoid most of the brush. The Boulder Creek Lakes are tucked into a granite bowl with excellent views to Little Granite Peak and Sawtooth Mountain across the canyon. Mount Hilton looms above and the granite slabs surrounding the basin create a magical setting. From Boulder Creek Lakes it’s back on trails. The initial descent to the Canyon Creek is fairly rough and rocky trail but the final few miles along the Canyon Creek Trail are relatively smooth and easy trail miles.    Topping out at just over 9,000 feet, the height of the Trinity Alps is not impressive when compared with the Sierras, but their higher latitude and proximity to the Pacific Ocean allow for significant winter snow accumulation and the existence of a few small patches of permanent ice. The largest of these patches of permanent ice is immediately below Thompson Peak and contains the requisite characteristics to be classified as a true glacier. Known as the Thompson Glacier, this glacier has undergone significant reduction in thickness and surface area as shown in this comparison of photos from the summit of Thompson Peak in 2013 and 2015 (both Labor Day weekend). The ongoing drought and a warming climate mean this glacier is in jeopardy of disappearing entirely. Glaciers were an integral part of shaping the majestic Trinity Alps that we see today with the ubiquitous ice-polished granite faces that embody these mountains, but if this glacier melts away the range would be devoid of true glaciers. thompson glacier comparison annotated

The Trinity Alps High Route is an excellent way to see some of the best scenery in the Trinity Alps. The Trinities may not stand out in the typical metrics used to rank mountain ranges, but the uniquely rugged granitic landscape and a true wilderness experience makes this a special spot. In fact, it’s one of my favorite areas to explore. This series of posts has described one route through these mountains, but the possibilities for wandering the lovely alpine terrain in this range are literally endless. I look forward to future trips to the Trinity Alps and hopefully uncovering more gems in this wonderful corner of California.

With awesome scenery and close proximity to the year around resort town at Mammoth Lakes, the Ansel Adams Wilderness is one of the most popular wilderness areas in the Sierra Nevada.  On any given summer day Thousand Island Lake is more aptly described as Thousand Person Lake. The reality is that Thousand Island Lake has far fewer than a thousand islands (actually only a few dozen) and most summer days people easily outnumber islands. However, the Ansel Adams Wilderness spans 231,533 acres and it’s remarkably easy to find solitude outside of the narrow corridor along the Middle Fork San Joaquin River, which includes Shadow Lake, Garnet Lake and Thousand Island Lake.  I have visited the Ansel Adams Wilderness over a dozen times, each time venturing beyond the well-trodden path to visit remote lakes and peaks including Mount Ritter, Banner Peak, Clyde Minaret, Mount Davis, Rodger Peak, Electra Peak, Foerster Peak and Volcanic Ridge. The Ansel Adams Wilderness never disappoints!  On this day I designed a loop that mostly features places I have already been to in the past (often multiple times), but it was amazing to combine these favorites into one aesthetic loop and see some of the best scenery in this region of the High Sierra. Starting from Agnew Meadows I headed down to the River Trail and then up to Shadow Lake in the pre-dawn hours. I timed sunrise nearly perfectly at Lake Ediza and then found a lovely tarn above the lake (marked on the USGS topo maps) to enjoy early morning light over the peaks and reflecting in the water, in the process taking over 100 photos in about 20 minutes!  This tarn overlooks Lake Ediza for a tiered view and includes the Minarets, Mount Ritter and Banner Peak. From the tarn I continued up slabs and talus to Volcanic Ridge which is one of the best viewpoints in all of the High Sierra. The tremendous panorama includes the best view of the impressive Minaret spires. From the summit of Volcanic Ridge I headed down the southwest slope toward Minaret Lake and then toured the triumvirate of three spectacular lakes beneath the Minaret spires – Minaret, Cecil and Iceberg. Each of these three lakes is stunning and provides a different angle on the Minarets which soar above the lakes like sky scrappers. From Iceberg Lake I traversed the basin above Lake Ediza and then headed up through meadows toward Mount Ritter and Banner Peak. The meadows ultimately transitioned to talus, but I was pretty good at avoiding any loose rocks making for an efficient climb to the snow chute leading to the Ritter-Banner Saddle. The steep now chute required crampons and ice axe. From the saddle, Banner Peak is a short talus hop away and soon enough I was looking down at Thousand Island Lake and Garnet Lake from the high perch. Mount Ritter is more complex. Unlike the past two times I had done the north face route, the snow had completely melted off the ice requiring a semi-sketchy crossing of hard, steep ice in aluminum crampons to reach the ramp for the north face route. This proved to be the crux. Once I was on rock, I encountered no further difficulties on the enjoyable class 3 scramble as I have done this route twice before and I was soon enjoying the view from Mount Ritter’s summit. This might be the year the snow and ice completely melts off and crampons and/or ice axe are not needed for the chute or to access the north face of Mount Ritter. It’s unclear whether the underlying loose rock would actually make the route more difficult. After the summits of Banner Peak and Mount Ritter, I headed down to the Ritter Lakes via Mount Ritter’s west slope. The west slope route poses no technical difficulties, but it’s important to follow the route as it’s fairly easy to wander off into much more difficult terrain. The west slope essentially utilizes two bowls connected by a slabby ramp. Finding and using this ramp is the key. The west slope descent route deposited me at the Ritter Lakes were the only spot I had not visited previously. I had high expectations as I first became intrigued while looking at them from Mount Davis. The Ritter Lakes did not disappoint as the wild and rugged character of the basin was breathtaking. These pristine lakes range in color from sapphire blue to bright turquoise. The uppermost lake beneath Neglected Peak is strikingly turquoise. From the Ritter Lakes I traversed to Lake Catherine which had excellent late afternoon light and then headed over North Glacier Pass and down to Thousand Island Lake for a pleasant early evening stroll along the entire length of the lakes north shore. I completed the loop by taking the River Trail bac to Agnew Meadows. 

The Drain & Ventana Spires

This post covers the first in a series of routes in the Ventana Double Cone region which features arguably the most rugged and wild coastal terrain in the contiguous United States. This first route is a repeat of “The Drain” route I did last year with Joey Cassidy with a mini-loop addition to visit the “Ventana Spires” which are stunning rocky pinnacles situated on a narrow ridge across from Ventana Double Cone with the headwaters of Ventana Mesa Creek in between. The next two posts will detail (1) the Ventana Triple Crown which is a spectacular high ridge traverse from South Ventana Cone to Ventana Cone to Ventana Double Cone and (2) a point-to-point route up beautiful Ventana Creek past 50 ft Ventana Falls to The Window (aka La Ventana) and Kandblinder carrying over into the Little Sur drainage to finish at Bottcher’s Gap.  Strava GPS route for the Drain and Ventana Spires hereMy route on this day was a repeat of the Drain Route from April 2014 plus a mini-loop to visit the awesome Ventana Spires.  The Drain became one of my favorite routes that I’ve done when I did it in April 2014 so I knew it was amazing, but I was still in awe of the sheer ruggedness and beauty of the cirque between Kandlbinder and Ventana Double Cone on the second time. In fact, this time may have been more enjoyable knowing that the route would go without issue. The Ventana Creek cirque provides a real sense of adventure in a truly wild canyon that is rugged and unspoiled and it was a pleasure to revisit. A route description and more details on the Drain route between Kandlbinder and Ventana Double Cone can be found here, but I’ve included a whole bunch of photos in this post from this year’s trip through the drain.    After completing the Drain route and topping out on Ventana Double Cone, I descended into the headwaters of Ventana Mesa Creek via an efficient gully through Santa Lucia Fir groves and talus. From the creek I took another steep talus gully with some rock scramblingn up to the Ventana Spires, which have remarkably rugged and precipitous SE faces. “Ventana Spires” is an unofficial name for these rocky pinnacles, but seems very fitting. Their position in the most remote region of the wilderness makes them particularly special. Few people have have stood atop the spires. There are three prominent points along the ridge make up the Ventana Spires and I’ve chosen to call them the north, middle and south Ventana Spires. The spires increase in height from north to south. From the north spire the ridge continues north gradually losing elevation on terrain that looks fairly brush free; a potential future project to explore down the ridge. Drain Spires routeDrain Spires route closeThe middle spire has an impressive view of the south spire with the wild east fork of Ventana Creek in the background. The south spire has perhaps the most dramatic view looking back to the middle spire and its sheer SE cliffs. All of the spires have amazing views across the expanse of wilderness and Santa Lucia Firs to Ventana Cone including the intermediary summits I dubbed “Lion Rock” and “Ventana Knob.”  I traversed the two highest spires (Middle and South) and then descended to the saddle between the Ventana Spires and Ventana Double Cone (VDC). Last time I experienced some thick brush in this section, but this time I was able to avoid most of the brush by staying on the south side of the ridge where there was a corridor of brush free scrambling between the cliffs and the brush. The 3rd class scrambling on the Ventana Spires traverse and the East Ridge of VDC were highly enjoyable in a stunning setting. I enjoyed the afternoon light from VDC and then began the trail run back to Bottcher’s Gap along the Ventana Double Cone Trail to Pat Springs and the Skinner Ridge Trail from pat Springs to Bottcher’s Gap. The Ventana Double Cone Trail from the summit to Puerto Suello Gap was characteristically overgrown. As usual, the cold and clear water at Pat Springs was a most welcome sight. Strava GPS route for the Drain and Ventana Spires here

Red Mountain Basin Loop

I visited Red Mountain and Hell for Sure Lake around the same time of year in 2012 and had an awesome time so I was looking forward to returning. This time I would ascend Mount Henry at the northern end of the Le Conte Divide with a striking vantage into Piute Canyon and the rugged section of the Sierra Crest in the John Muir Wilderness. As I wrote in 2012, the Le Conte Divide is an often overlooked area west of the Sierra Crest that features spectacular scenery and numerous opportunities for off-trail exploration making this region particularly suitable to adventure running. The divide forms the boundary between the John Muir Wilderness to the west and Kings Canyon National Park to the east. Geographically, to the east is the impressive Goddard Canyon and to the west is a series of spectacular granitic basins with dozens of pristine alpine lakes including Red Mountain Basin, Bench Valley and Blackcap Basin. The peaks on the divide are quite rugged, especially on their north and east sides, which belies the fact that these summits are only around 12,000 feet in elevation and higher neighbors to the east are well over 13,000 feet. Once again, elevation is not everything. The Le Conte Divide also one of the more remote sections of the range and therefore solitude can easily be achieved. The region is guarded by a long approach most often reached from Courtright Reservoir with a minimum of 15 miles on trail just to reach the basins. The long approach is ideal for adventure running as they are fairly moderate (runnable) and are within the pleasant montane forest zone for a large portion. Since the LeConte Divide is so remote, only a handful of peaks have names and the remainder are simply identified by their altitude. The basins to the west of the divide are quintessential Sierra scenery with dozens of gorgeous alpine lakes, tarns and meadows. GPS route here.

On this trip I covered familiar ground for the first 12 miles to the junction with the Hell for Sure Pass Trail. Instead of turning right I continued straight covering new trail to Indian Lakes. From Indian Lakes I headed off cross country through forest that transitioned to grassy benches and granite slopes that led to the West Ridge of Mount Henry. Staying on the crest of the ridge yields some class 3 scrambling. An easier route that I took on the descent is to utilize a chute to access the West Ridge further up. Either way, all of the scrambling is on the lower part of the West Ridge as the upper part transitions to easy talus hopping. Mount Henry’s position at the northern end of the Le Conte Divide provides a stellar view of surrounding mountains, especially looking west into Piute Canyon and the range of peaks from Seven Gables to Bear Creek Spire to Mount Darwin.  I would put htis view up among the classics, with incredible relief from canyon to peak and lots of intricate layers in the terrain. Moreover, remote Lake 10,223 provides makes for a beautiful subject in the foreground. I spent a lot of time photographing and enjoying the marvelous vantage. On the descent I veered off the west ridge at its low point via a loose chute and then easy grass terrain down to aptly-named Turf Lakes with an expansive chunk of tundra between the lakes. From Turf Lakes, I embarked on an easy cross country traverse to Davis Lake and up Red Mountain. On Red Mountain I took the north ridge which had some fun solid scrambling instead of the loose west slopes which looked like a real slog. Red Mountain had the same great views I remembered from 2012, especially looking up Goddard Canyon to Mount Goddard and the Hell for Sure Lake Basin. A use path exists from Red Mountain down to Hell for Sure Pass and from there it was all trail back to Courtright Reservoir. In the future I hope to revisit the Le Conte Divdie for explorations of Bench Valley and Blackcap Basin. I would also like to revisit Red Mountain basin for further exploration including an ascent of Mount Hutton and stops at Devils Punchbowl, Little Shot Lake and Big Shot Lake. GPS route here

Ericsson & Genevra

Mount Ericsson and Mount Genevra are two points along the rugged and immensely scenic Kings-Kern Divide which is a high barrier between the Kern River watershed and the Kings River watershed, two of the three important watersheds in the Southern High Sierra (the other being the Kaweah River). The point separating these three watersheds is aptly-named Triple Divide Peak along the Great Western Divide, which I visited last year. The Kings-Kern divide also serves to connect the Sierra Crest with the Great Western Divide and marks the border between Sequoia National Park and Kings Canyon National Park. Foerster Pass, the highest point along the Pacific Crest Trail at over 13,000 feet, is the only trail that crosses the Kings-Kern Divide, although there are a number of other cross country passes of varying difficulty. I have spent quite a bit of time in this area. In 2009 I did an aesthetic loop crossing through Milly’s Foot Pass to visit Upper Kern Basin and Lake Reflection for the first time. Last year, I climbed Mount Stanford, the highest point on the Kings-Kern Divide via Harrison Pass. On this trip I gained the divide via a little known route from Lake Reflection and then climbed Mount Ericsson. I then traversed the upper reaches of Kern Basin to Mount Genevra and descended Milly’s Foot Pass back to Lake Reflection, a jewel of the High Sierra. The route also included passage by lovely East Lake. GPS route here.While numerous cross country passes cross the Kings-Kern Divide, perhaps the second easiest route over the divide (after the Foerster Pass trail) is not a pass at all but a little known route over a high shoulder east of Lake Reflection, an unnamed point I like to call “Reflection Point”. This route takes an efficient class 2 avalanche chute all the way up and over the divide, lacking the unstable talus, scree and sand of the nearby passes, including Harrison Pass, Lucy’s Foot Pass, and Milly’s Foot Pass. More importantly, the Reflection Point route affords astounding views of Lake Reflection the Great Western Divide for its entire length. Mount Brewer and the Guards rise sharply above Lake Reflection with granite virtually everything in sight. A high shoulder marks the top of the chute where the climber is steps away from Reflection Point and a marvelous view that is better than most named summits. The south side of the pass is an easy descent into Kern Basin on gravel and meadows. The key to the Reflection Point route is finding the correct chute since more difficult terrain lies nearby and technical terrain is not much further.  Once in the chute, the terrain is mostly slabs all the way up (make sure to stay in the central wide chute) and goes as class 2 the entire way. On this day I used this route to access Mount Ericsson, centrally located on the Kings-Kern Divide with an excellent 360 degree view including the entire Sierra crest from the Palisades to Mount Whitney and the Great Western Divide from North Guard to Milestone Mountain. Once at the top of the route, it’s an easy stroll down to the top of Lucy’s Foot Pass with stunning views of the jagged Ericsson Crags.

At Lucy’s Foot Pass, you’re at the base of Mount Ericsson which goes as a class 2 talus slog with a little bit of class 3 at the top.  Mount Ericsson’s central location affords an amazing view of the entire southern Sierra. Ericsson’s most distinctive feature is its serpentine south ridge with numerous rocky ribs extending deep into Kern Basin. Of the sea of peaks surrounding Mount Ericsson, the closest and easiest is Mount Genevra across the upper reaches of Kern Basin. Mount Genevra also happens to be above Milly’s Foot Pass which provides passage through the Kings-Kern Divide back to Lake Reflection. Milly’s Foot Pass includes a sketchy 3rd class chute at the top where one must be cautious of kitty litter over the rocks, especially while descending. The remainder of the descent from Milly’s to Lake Reflection involves plenty of arduous talus, but there are some pretty alpine tarns midway down the descent. While Mount Genevra is much lower than Ericsson, its position provides very nice views to the Mount Whitney region and the Great Western Divide. My favorite angle was down the East Creek drainage including Mount Bago towering above East Lake. Perhaps the most endearing location on this route is Lake Reflection, one of the greatest gems in the Sierra. While I have visited Lake Reflection twice before, this was my first time for early morning light to see the exquisite reflections for which this lake is named. The early morning reflections did not disappoint and some new snow lining the cliffs of Mount Genevra and Mount Jordan only added to the tremendous setting. East Lake, located a couple miles before Lake Reflection, is also an excellent destination with beautiful views and reflections. It’s about 11 miles to Junction Meadow along the Bubbs Creek Trail. At the meadows, turn right onto the East Lake Trail which shortly crosses Bubbs Creek (can be hazardous in early season) and then begins and ascent to East Lake, reaching East Lake about 13.5 miles from Road’s End. After East Lake the trail becomes faint in spots manifesting the lack of visitation to this region, but the idea is to generally follow the watercourse upstream and in a couple miles the outlet of Lake Reflection is reached. At first glance, Lake Reflection might seem small, but this is only the outlet bay. A few meters away lies a log jam and views of the expansive alpine lake. GPS route here.

Electra Loop – Electra Peak & Lyell Fork Merced River

The Lyell Fork of the Merced River is one of the most remote and rugged regions in Yosemite National Park. Any approach requires many miles on trail followed by off-trail travel. The lower part of the drainage features a splendid series of meadows as the river snakes through a grassland with an amazing view upstream to the chiseled rideline including Mount Ansel Adams and Electra Peak. Higher up in the basin, the forest thins and the terrain transitions to a granite playground with a series of spectacular alpine lakes. It seems as if each lake has a different color, from midnight blue to milky turquoise.  It’s not entirely clear to me what is responsible for producing the different colors when the lakes are all connected and in such close proximity, but the resulting palette is magical. At the highest reaches of the basin the terrain is entirely devoid of vegetation and the uppermost lakes sit in a strikingly barren landscape of talus and granite. Above these uppermost lakes is the roof of Yosemite, Mount Lyell, at 13,120 feet above sea level and the highest point in the national park. I have looked down into the Lyell Fork of the Merced River from numerous points including Mount Lyell, Foerster Peak and Rodgers Peak and I have always wanted to explore the basin. In order to accomplish this goal, I designed an aesthetic loop out of Tuolumne Meadows that would include the Lyell Fork of the Merced River and also the summit of Electra Peak, one of the more remote summits in Yosemite with a grand view of the region. Since Electra Peak is the central feature of the route I called it the “Electra Loop” and entails nearly 44 miles and close to 10,000 feet of elevation gain. The loop is similar to the Roof of Yosemite Loop I did earlier this year but is a bit longer to incorporate the Lyell Fork Merced River and Electra Peak. GPS route info here.

The route starts with a trek up Lyell Canyon on the John Muir Trail, one of the most runnable stretches of trail in the High Sierra. At the head of the canyon is a climb up to Donohue Pass with an excellent view of Mount Lyell and Mount Maclure. Soon after Dononhue Pass leave the trail and head south through easy alpine terrain to the meadows beneath Marie Lakes where the Marie Lakes trail is intersected. A short climb on this trail brings one to Lower Marie Lake. From here continue cross country up a ridge on the south side of the lake and then traverse granite and talus slopes to North Clinch Pass. Lower Marie Lake is a large body of water and includes stupendous views of Mount Lyell and also across Rush Creek basin to Donohue Peak and Mount Andrea Lawrence. The narrow ridgeline is particularly scenic with a “secret Marie Lake” visible deep in a granite bowl. The direct route over North Clinch Pass includes some class 3 scrambling on its south side but it looks like a somewhat circuitous detour south along the ridge could eliminate the class 3 altogether. Passage through North Clinch Pass brings one into the remote upper reaches of the North Fork San Joaquin River. This drainage, like the Lyell Fork of the Merced River, is rarely visited but a real gem of the High Sierra. My passage through this basin was at its uppermost reach via a high traverse to Electra Peak on talus and granite slabs. I could see the numerous inviting lakes below, but my path would remain above them.  I look forward to visiting these lakes in the future. in fact, the High Sierra Route passes through perhaps the most dramatic part of the North Fork San Joaquin River drainage as it descends from Lake Catherine and traverses to Twin Island Lakes with wild views of the North Fork San Joaquin River Canyon and Mount Ritter and Banner Peak towering above. After the traverse of the headwaters of the North Fork San Joaquin River to Lake 11,815, the climb of Electra Peak’s north ridge is a straightforward scramble on talus and then some rock on the final portion on the ridge. The view from the summit is incredible and takes in a 360 degree panorama encompassing everything from Half Dome to the Clark Range to Mount Lyell to Ritter and Banner.  The best view in my opinion looks down the Lyell Fork of the Merced River with it’s numerous colorful lakes and beautiful meadows. From the summit, descend Electra’s northwest slope (talus and slabs) to Lake 10,999, a deep blue lake situated in a barren granitic landscape. Descending down the drainage from Lake 10,999 leads to Lake 10,702 tucked in beneath a rugged ridge extending to Mount Ansel Adams. A descent down a minor headwall beneath Lake 10,702 leads to a lake with striking bright turquoise color. This lake is not even assigned an elevation on the topo maps, but is one of the unique highlights of this region. The next lake on the trip down the Lyell Fork is perhaps the most spectacular and is labelled as Lake 10,217 on the topo map. This lake retains some of the turqouise color as the previous lake but has a bit more of a blueish tint. The lake also includes more vegetation along its shores, an alpine beach, and an elongated shape that makes it look like a swimming lane with Mount Ansel Adams and Foerster Peak towering above. This is certainly a spot I could spend some time relaxing!  Below Lake 10,217 is the primary headwall of the drainage and includes a fair amount of micro-navigating to avoid small cliff bands (although numerous routes are available). Below the headwall, travel becomes easier through open forest eventually reaching the splendid meadows. From the meadows it’s about a mile downstream through forest and granite slabs to the Isberg Pass Trail which is taken north to the Lewis Creek Trail. The ascent up the Lewis Creek Trail leads to Vogelsang Pass and then down the Rafferty Creek trail back to Tuolumne Meadows. GPS route info here.
