Ascent Trip Report

East Ridge Ascent

Took Commonwealth Basin trail to the PCT freeway eventually exiting at Bumblebee Pass and following the steep climbers trail up to the pass. There is basically a well tread trail that descends from the pass to the basin and up to the large grassy notch on the east ridge. The basin had plenty of running water. Once on the ridge, there was another climbers trail that led up to the summit block; although much more braided. At the block, done with class 2 terrain, proceeded left (right sucks) and up blocky steps towards a small break in the above tree band continue on the best rock through a second tree band. Above the tree bands and at the next wall go left more than you think, that will bring you to the infamous class 4 section. Plenty of hand holds and foot holds makes for a simple ascent. The summit is only a minute or two from that section. I down climbed the class 4 section but had a 30m handline and anchor material with me. There are plenty of foot holds and using the chimney nature of the feature to brace yourself worked well. Felt like a fun boulder problem... without the soft landing. There is a flat area below the section for a partner to stand and help spot or provide a sturdy pair of shoulders as a step; a good partner. Back at the PCT, I hightailed it over to Alaska Mountain to make better use of that long approach.
