"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
"Drove up from Seattle at 5am, started hiking steeply uphill from the car at 9am, no snow until much higher. After about 1500 feet put on skins. Headed up the avvy path under Burgundy and then traversed over to ascend the to the glacier and col below the summit. From there we left our skis and scrambled up steep snow and rock. Reaching the summit block required some sketchy unprotected moves in snowboard boots. Incredible panoramic views at the top. Sticky mashed-potato conditions for most of the way down, lots of avvy debris in the gullies. LOONG skin and hike down to the car, 8 hours car to c" - Silver Star Mountain, hauteroute, May 27, 2017
"Had an awesome time climbing Mount Stuart via the Cascadian Couloir with my buddy Paul. We hiked in and camped at Ingalls Creek last night. We started climbing at 3am with the headlamps out and got to watch a killer sunrise as we were leaving the top of the couloir. We were the first party at the summit and had it to ourselves the entire time we spent up there. Second tallest non volcanic peak in Washington. And the delicious bonus was that I finally got to eat a Mount Stuart Burger from Mountain High Hamburgers after climbing Mount Stuart. " - Mount Stuart, Al-Rashid, Sep 10, 2016
"Headed up Torment Creek, then followed the ridge line above Moraine Lake to the west. Camped near Point 7252. In the morning, headed out at 7 AM following the ridge west. Got on the Inspiration Glacier near Point 7292. Very few crevasses. Some of us summited the Eggplant (Point 7733). Dropped some gear and joined the standard ascent route. Summited at 1 PM. Knife Edge was not very edgy. Took the standard route down Eldorado Creek back to the trailhead." - Eldorado Peak, mathiasricken, Jul 24, 2016
