Day 3 of the alt Sierra Challenge 2013. While the hard core Challenge nuts crossed the crest at Echo Col and head for bad weather on the Black Divide, seven of us (Laura, Joan, Tommey, Carol, Jeff, Jim, and I) headed for Ski Mountaineers peak first followed by Mt Thompson via its tricky but highly satisfying north ridge. Once on top, Tommey continued on to Pt Powell while the others returned the way they came. I continued the grand loop by dropping down Thompson's horrible SE chute and climbing the only weakness (a class 2 chute) on Mt Gilbert's west side. Bypassing the summit due to bad weather (and having climbed it before), I climbed over Mt Johnson (with thunderstorms both north and south of me) before returning via the Treasure Lakes basin.
