Junipero Serra Peak

It’s fairly rare for a modified arctic cold front to sweep into central California. However, in early December a cold, dry continental airmass overspread the region. With the cold air in place, attention turned to the possibility of low elevation snow on local mountains. All we needed was moisture. It seemed like wishes would come true with a system coming in from the north late in the week. In fact, the National Weather Service office in Monterey issued a winter weather advisory two days out from the event, specifically calling out the Santa Lucia Mountains for up to 6 inches of snow. Stoke level was high for a snow day on Cone Peak’s Stone Ridge. Well, things didn’t turn out as initially forecasted and the winter weather advisory did not verify. Snow levels wound up being much higher and only the highest peaks in the Santa Lucia Mountains received snowfall (>4,500 ft). Why?  The low pressure tracked from near Crescent City, California to Lake Tahoe placing the central coast on the south side of the low. In this sector, onshore winds brought in relatively mild air off the Pacific Ocean just as the heaviest precipitation arrived. In fact, temperatures increased as the event unfolded despite it being in the middle of the night. Once the cold front passed, snow levels plummeted once again, but by then very little moisture was left. All things considered, it seemed highly unlikely snow accumulated on Stone Ridge between 2,500-3,800 ft (we were right).  At this time Joey came up with a plan B – Junipero Serra Peak. As the highest point in the Santa Lucia Mountians at 5,862 ft, Junipero Serra Peak stood the best chance of having some snow accumulation. The route would be only 12.4 miles roundtrip but feature over 4,000 ft of climbing.  It turned out to be a great idea!   Strava route here

The group for this adventure included Joey Cassidy, Flyin’ Brian Robinson and Brian Rowlett. From the trailhead we could see some snow accumulation on the summit, but we were not prepared for how remarkably awesome the wintry scene would become on the last thousand feet of vertical on the mountain.  As we ascended above the snow line, we found a unique combination of snow, rime ice, and glaze ice (from freezing rain).  It felt as if we were entering an ice box as everything was glazed in ice, sometimes approaching over an inch thick.  I have never seen so much ice accumulation!  After ascending to the summit ridge, we traversed to the north side where we hiked through a coniferous forest which had become a winter wonderland with snow and ice covered Coulter Pines (largest pine cones in the world, weighing up to 8 pounds!) and Sugar Pines (the longest pine cones in the world, growing up to 24 inches long).  The entire mountain was burned in the Basin Complex Fire in 2008, but it’s good to see a large portion of the conifer grove survived the fire. In fact, Coulter Pine saplings were thick in spots. The chaparral slopes on the mountain did not fare as well with virtually all of the older woody chaparral charred. Five years later new chaparral vegetation is growing back aggressively, but the old burned snags remain making for an interesting sight when glazed with ice.

The flora and fauna of the Santa Lucia Mountains is often rare and fascinating. The pine forest of Coulter Pines and Sugar Pines atop Junipero Serro was so striking I decided to do a little research. It turns out Sugar Pines are not common in the Santa Lucia Mountains and can only be found on a few of the tallest peaks in the range, including Cone Peak and Junipero Serra Peak. The grove at Junipero Serra is particularly large with several tall old-growth trees.  Interestingly, the Sugar Pines in the Santa Lucias are genetically distinct from other populations of Sugar Pine due to large geographic separation. The two populations cannot mix. I wonder how these trees got the summit area of Junipero Serra in the first place as everything surrounding the grove is either chamise or montane chaparral. 

Another favorite topic of mine is meteorology. What caused such an impressive accumulation of glaze ice on Junipero Serra? As mentioned above, the weather system that pulled in some relatively warmer air off the Pacific in the middle and upper levels of the atmosphere, but colder air lingered at the lower levels of the atmosphere. Rain droplets formed in the warmer clouds but then became supercooled when they descended into the colder air below and froze upon contact with any object on the upper part of the mountain. This is freezing rain. The resulting ice from freezing rain is aptly named glaze ice and was at least an inch thick in spots. After the cold front passed on Saturday night, the entire atmosphere became cold enough to support snowfall on the highest elevations of Junipero Serra. This phase of the storm dropped 3+ inches of snow to complete the unique winter wonderland scene.  

While I’m a big fan of winter sports in general, seeing places snowcovered that don’t typically receive much snow is always a special experience. After this adventure I’m even more pumped for the winter season and the potential for a few more chances to see local mountains snowcovered. You can bet I’ll be chasing the snow!
