"I’d like to think I made history with this one. After a huge Italian dinner and beers, we casually decided at the midnight hour, “let’s do Dragontail tomorrow”. The prior 2 big days had started to take their toll, but the beer was talking now. Only thing: I had a catch a flight back to SF the next evening. If we went for Dragontail, we’d have to book it. I was skeptical. But Josh just said, “Let’s do it.” On the trail to Colchuck Lake at 6:30am. We flew up, under 1 1/2 hrs to the lake. I ran out of steam a bit on Aasgard while Josh surged ahead and flashed the whole pass climb in 40 min" - Dragontail Peak, scott, Sep 9, 2018
"Overnight trip, camped at Wing Lake. Nearly solid snow cover starting at Heather Pass, even though the summer trail is beginning to melt out. 4 AM alpine start, perfect cramponing snow. Scramble was easy for the most part, although we went into the wrong gully once (too far to the east). The crux move just under the true summit is a little sketchy, but the rock is solid, and there are hand- and footholds if you take your time." - Black Peak, mathiasricken, Jul 8, 2018
"Camped at Stuart Lake. Hiked to Colchuck Lake and ascended Aasgard Pass, then west southwest to the col near the main high point. From there, scrambled up to the summit. Descended the same way, since the snow going up Pandora's Box was too slushy for us." - Dragontail Peak, mathiasricken, May 26, 2018
"Climbed the CC solo as a dayhike. Absolutely gorgeous area with stunning views of Rainier and the Enchantments. I was able to avoid alot of the loosness staying on steeper granite. Didn't touch any snow and a fun scramble from the false summit. Stoked to have Stuart as my 100th peak." - Mount Stuart, MatthewWinterberg, Aug 14, 2017
"Started out on July 31, 2017 in the middle of one of the worst heat waves in Washington State history. We encountered dense smoke from a series of forest fires in the Pacific NW, mostly from British Columbia. We were going to attempt either Shark Fin Tower or Forbidden on August 1st but bailed on both after assessing the smoke (code red air pollution) and rapidly melting glaciers and snow fields. The snow patches below the main tower on Shark Fin would have been hazardous even with crampons and ice axes (too slushy). The climber's route trailhead to Forbidden was 92 degrees at 4 pm on July" - Forbidden Peak, tlannin, Aug 1, 2017
