Now that is a fantastic route! Trip report.
Team of three as a day hike
Skiing the N couloir. Actually turned a bit scary as I was too early in the day and the couloir had not not yet developed corn and stayed icy. Should have waited at least another hour.
A good scramble up the NW ridge from Treasure Col, though I found this page's description to be somewhat misleading. You aren't on the spine of a continuous, well-defined ridge the entire time. It actually flattens out for a good while in the middle of the traverse and becomes more class-2ish. But the upper third is pretty sweet stuff.
Good to see a summit register more than a decade old (1975 in this case).
2nd class talus slog. it took us 2 hours to get to the summit from Treasure Lake.
Thunderstorms abound in the Sierra, we managed to bag 3 peaks this day with Peak 12,650ft. and Gilbert, the scramble up Johnson was very solid and fun with a short knife edge finish.
Began ascent up west slope then got onto NW ridge. Fun fun!!! Managed to beat the storm off all 3 peaks and enjoyed a little hail shower through the morraine.
This was a very fun scramble with a few airy moves. It's every bit as good as the page author claims, and it is true that you never have to leave the ridgeline.
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. Pictures & Story
Climbed this as an alternate (easier) peak on day 4 of Burd's 2012 Sierra Challenge. Went up the sandy chute on the southeast slope -- described as class 2 by Secor, but the top 100-200 feet seemed to me to be class 3. Easy climbing but no exposure. I was the 6th person to sign the register this year.
Scrambled up the Northwest Ridge with Amy. Great route!
Over from Bishop Lake to Treasure Lake and up the east ridge. I do not recommend this route.
A fun scramble from Treasure Col after doing Gilbert's north couloir. Suncups weren't as bad as I feared on the way down. Trip report
The skeeters devoured me at Treasure Lakes, the sun-cups, kicked my ass, but the ridge was worth it. The ridge is harder 3rd, sometimes very exposed, and requires good route finding. I descended the Southeast Slopes for an easy quick escape.
From Treasure Lakes. I was aiming for the quickest way out of all those boulders, so I chose the northeast ridge. Fun scrambling near the top.
Day 6 of the 2008 Sierra Challenge. Climbed the East Face of Hurd in the morning with Brice W, then traversed to Trapezoid via the South Ridge of Hurd and Trapezoid's NE Ridge (the South Ridge was a better scramble). Met up with Adam J on Trapezoid and traversed the crest to Johnson. Fun day. Trip Report
Climbed S. face of peak 12,600 just N. of Johnson first,fun cl. 3 climb with a 70's register. Then it was off to Gilbert and peak 12,800. I then traversed back to Treasure Col and climbed the N. Ridge of Johnson which was as good as advertised.
2008 Sierra Challenge. After climbing Trapezoid Peak I started to traverse the connecting ridge but this turned out to be quite tedious and slow (maybe I was just not in the mood any more for much more ridge climbing). So I dropped down into the cirque and ascended the SE slope.
Long and sandy, but some fun scrambling near the top.
