Backpacked on the Cottonwood Pass Trail to the PCT and on to camp at Soldier Lake. Carried our packs up the trail to Army Pass, then left them while we climbed to the summit of Mount Langley. We hiked down to our backpacks, then descended to the Cottonwood Lakes via Army Pass and spen the night next to one of the unnamed Cottonwood Lakes. Headed out to the car on the Cottonwood Lakes Trail the third day. Great loop hike!
