The easternmost part of the Trinity Alps is informally known as the Red Trinities due to the distinctive red rock present in this region. However, within the red rock is a section of white granite that is akin to the White Trinities to the west. This white rock stretches from Granite Lake to Gibson Peak to Siligo Peak, and not surprisingly, this area of white rock is also the most rugged part of this region. The transition between the red and white rock is very well defined creating a fantastic juxtaposition. The Four Lakes Loop is located in the heart of the Red Trinities and offers a particularly striking tour of this geologically complex region. The loop is essentially a circumnavigation of Siligo Peak passing by four alpine lakes that surround the mountain. The loop itself is only around 6.5 miles but the entire loop is deep within the Trinity Alps Wilderness and access to the loop is through one of five trails. The shortest and most efficient is the Long Canyon Trail at 6 miles (18+ miles total for the loop and access), but other options include the Stoney Ridge Trail, Granite Lake Trail via Swift Creek, Deer Creek Trail via Stuark Fork Trinity River, and Bear Basin. The land is not as rugged as the neighboring White Trinities, but it has a unique and charming character that is spectacular in its own right. The Four Lakes Loop is a wonderful introduction to the region and has new and spectacular scenery around seemingly every corner.
The author accessed the Four Lakes Loop via the Long Canyon Trail so the following is a description of that route. The Long Canyon Trail is a steady climb through conifer forest before emerging into meadows beneath striking Gibson Peak. It is here where one may encounter fields of Anemone occidentalis, or the western pasqueflower. The pasqueflower produces a fruit called an achene that is ellipsoid in shape and feather-like. This furry fruit reminds people of the truffula trees in Dr. Seuss’s The Lorax. The flower and its whimsical late summer fruit can be found in open rocky slopes and alpine meadows in the trinity alps and one of the best places is the meadows in upper Long Canyon and the slopes above Deer Lake. The meadows continue all the way to Bee Tree Gap, where one obtains a view of Siligo Meadows and the spires along Gibson Peak’s west ridge. After about a mile traverse above Siligo Meadows one arrives at Deer Creek Pass and is treated to a wonderful view of Deer Creek and the glacier carved U-shaped valley of Deer Creek. Here the striking juxtaposition of red and white rocks becomes apparent as red rocks fill the basin around Deer Lake but Siligo Peak possesses a distinctively white summit area.
A switchback beneath Deer Creek Pass is the junction with the Four Lakes Loop. Doing the loop clockwise, one makes a lovely traverse through the red rocks above Deer Lake and up some switchbacks to the south shoulder of Siligo Peak. The trail passes through wonderful meadows stretching down to Deer Lake and including more pasqueflower. At the shoulder of Siligo Peak a use trail departs up the ridge to 8,162 ft Siligo Peak. In only a quarter mile the trail reaches the summit which contains a gorgeous 360 degree panorama of the region. To the west one has a birds eye view of Diamond Lake, the Stuart Fork of the Trinity River canyon, and the White Trinities. All of the major peaks of the White Trinities are visible including Mount Hilton, Thompson Peak, Caesar Peak and Caribou Mountain. Closest and most prominent is Sawtooth Mountain with its distinctive tooth-like summit block and a massive apron of white granite slabs on its east side. To the south is Summit Lake, Red Mountain and Middle Peak. To the east is a striking demarcation between the red rocks of Seven Up Peak and the rugged ridge known as Dolomite Ridge composed of the white rocks. To the north one peers into the glacier-carved Deer Creek canyon with Mount Shasta’s distinctive snow-capped cone rising above the ridges. Suffice it to say, the side trip to Siligo Peak is well worth the extra effort.
Back on the Four Lakes Loop one may make a side trip to Summit Lake which is the largest of the four lakes on the Four Lakes Loop. Continuing on, the loop drops into the Salt Creek drainage and switchbacks down toward Diamond Lake, which sits on a meadowy bench with the White Trinities towering across the Stuart Fork Canyon. This is lovely country with bountiful summertime wildflowers and outstanding scenery. From Diamond Lake it’s a gradual climb up to the northwest shoulder of Siligo Peak where one crosses into the Deer Creek drainage. From here the trail traverses above astonishingly beautiful Luella Lake which sits right at the line between red and white rock with Seven Up Peak and Dolomite Ridge making a dramatic background. Colorful Luella Lake sits at the base of the north face of Siligo Peak which contains mountain hemlocks and rugged cliffs. This steep north-facing topography enables snow to collect around Luella Lake and persist into late summer and sometimes year around. Beneath Luella Lake the trail descends into a valley in the upper reaches of Deer Creek Canyon. At the valley floor is the junction with the trail that goes down Deer Creek Canyon, which also provides access the route from Granite Lake and Swift Creek. Staying right to stay on the Four Lakes Loop, the trail makes a steep ascent up the headwall of Deer Creek through meadows and clumps of Mountain Hemlock to Deer Lake. The imposing cliffs of Dolomite Ridge dominate the view are along this section. From Deer Lake there’s one final climb to complete the loop and then reach Deer Creek Pass before a mainly flat traverse back to Bee Tree Gap and virtually all downhill through Long Canyon back to the trailhead. Total mileage of the Four Lakes Loop via Long Canyon is around 18 miles.
The area has numerous opportunities for exploration and one option is the following tour of three additional off-trail lakes that connects back to the Long Canyon trail. Instead of returning back to Deer Creek Gap, one may take the trail down to Siligo Meadows and then up to Little Stonewall Pass. Just beyond Little Stonewall Pass a usetrail branches out to Echo Lake, one of the more charming lakes in the region. Circle Echo Lake on either side and then ascend a chute with some loose rocks (off-trail) to a col on the crest. Descend talus and then traverse slopes north to Billy Be Damned Lake. From Billy Be Damn Lake it’s a short climb up and over to the magnificent Anna Lake, situated in a bowl of red granite slabs and mountain hemlock. From Anna Lake a faint use trail heads down a steep gully down to Long Canyon. The use trail ultimately disappears in the meadows, but the Long Canyon trail is visible below and the way is unambiguous. GPS route here.
