| Upper Crabtree Lake from Crabtree Pass |
We were out again in mid-August for another week in the backcountry, this time in the Southern Sierra. We've spent many days hiking and backpacking in this area over the years, but there were pockets of off-trail areas that we had missed, and beautiful places we needed to revisit. This part of the Sierra is much dryer than farther north and this late in the season we would need to be mindful of water resources. The areas we explored were the west side of the Sierra Crest between Cottonwood Lakes/Horseshoe Meadow and Mount Whitney. The only negative for the entire trip was intermittent drifting smoke from the Coffeepot Fire, about 30 miles to our west. Oh, and the wind and unseasonably low temperatures from the near record cold front that passed through on the last two days... Frozen water bottles in the morning, in August!
Day 1 (12 miles, 2,900 feet elevation gain). We began our day at the Cottonwood Lakes trailhead west of Lone Pine. We cruised the easy trail ascent to the lakes basin, then took the direct route up the Old Army Pass trail to the crest. Yes, there is a NEW Army Pass, and the original Army Pass. New Army was constructed in 1955 on a south facing aspect to avoid the snow choked original trail (constructed in 1892 when soldiers patrolled Sequoia National Park). They both gain the crest only about 1/2 mile apart, but the new trail is a longer slog to the top. This late in the season we had no problem getting up the old trail which was snow free and in relatively good shape (it no longer gets trail maintenance). From the crest we took a cross-country line below Mt. Langley to a point where we could drop on a faint use trail down to upper Soldier Lake. It was still early enough for some more miles, so we decided to head off again and into the incredible Miter Basin. With some off-trail adventuring we made it to the hanging valley Iridescent Lake at the northwestern edge of the basin for the evening.

Day 2 (6 miles, 1,250 feet elevation gain). This was an all cross-country hiking day with a tricky pass and route finding. We departed Iridescent Lake crossing the ridge just below The Miter and into the main Miter Basin near Sky Blue Lake. From there is was a winding ascent past many unnamed ponds and lakes to the base of Crabtree Pass. Gaining the pass was relatively straightforward, but the route down was steep and tricky in a narrow chute of sand, scree, and small talus. We took our time and after a few hundred feet of descent the slope eased and a use trail led us down to the inlet end of upper Crabtree Lake. We continued on to the middle Crabtree Lake and found a spot for the evening.

Day 3 (6.75 miles, 1,225 feet elevation gain). In the morning we continued down the canyon, past lower Crabtree Lake and on to lower Crabtree Meadow. Here we joined a formal trail that continued north to connect with the John Muir Trail (JMT) at upper Crabtree Meadow. This is a busy spot as Mt. Whitney hikers are passing through in both directions. From this point it's only about 8 miles to the top of Mt. Whitney. But we had no interest in that peak (been there, done that, many times) but wished to go off-trail again and see the Hitchcock Lakes basin just south of the Whitney trail. This secluded little spot is less than a mile from one of the busiest trails in all the Sierra, but during our afternoon at camp we only saw a couple of hikers who came over the ridge for a short visit.

Day 4 (13.5 miles, 2,000 feet elevation gain). This was our farthest north point for the trip, so it was time to turn back. From Hitchcock Lakes we backtracked to Crabtree Meadow then continued south on the Pacific Crest Trail. Before reaching Cottonwood Pass we turned west cross-country ending the day in Siberian Outpost. This high elevation windswept meadow at nearly 11,000 feet is stark and beautiful. From our windy camp we had a stunning view of the crest around Mt. Langley.

Day 5 (6.5 miles, 1,200 feet elevation gain). From our camp in Siberian Outpost we took a cross-country route up the valley and then up the headwall to the Boreal Plateau. The Boreal Plateau is a high elevation sky island bordered by the Kern River to the west and the Sierra Crest to the east. On the western edge of the plateau lies Funston Lake and we were keen to visit. This stark lake at 11,000 feet elevation is about as remote as it gets in this part of the world. After an early lunch at the lake we climbed back up to the plateau and crossed over to the Rocky Basin Lakes on the south edge. By mid-afternoon, and being unsure of water resources farther along the route, we pulled in to a small pond and meadow nestled in a lovely Foxtail and Lodgepole pine forest for the evening.

Day 6 (11 miles, 1,600 feet elevation gain). Get out day. From camp we continued the descent to Big Whitney Meadow. After a long traverse of the meadow (yes, it's really big), we started the climb back to Cottonwood Pass. Thankfully for these weary travelers it was a quick 4+ mile descent to the trailhead.
