  • Mount Stuart is the highest mountain in the Alpine Lakes Wilderness in the Cascade Range of Washington.
  • 2nd highest non-volcanic peak in Washington, after Bonanza Peak.
  • Like many Cascade peaks, Mount Stuart is more notable for its local relief than for its absolute elevation. The south face rises 5,000 feet in just 2 horizontal miles. The northeast and northwest sides of the mountain exhibit similar steep relief.
  • Due to its location away from higher peaks, Mount Stuart has 5,354 ft prominence, making it the 6th most prominent peak in Washington.
  • The rock of Mount Stuart is unusually rugged and unstable, due to the extensive jointing of the granite.
  • The standard route is the Class 3 Southeast Route up the Cascadian Couloir. It ascends the gully to a false summit just southeast of the main summit and finishes along a short ridge. The route involves scrambling, and often, steep snow.
  • More technical climbs can be found on the complex north face of the mountain, including the classic North Ridge (5.7).
"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." - MatthewWinterberg, Aug 14, 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. " - Al-Rashid, Sep 10, 2016
"After taking so many pictures of Mount Stuart during our summer hikes in the area, we decided to try and fit in an attempt before the the snows begins, and while there was a potentially decent two-day stretch of weather. There are a number of good resources that describe the "standard route," up and over Long's Pass and up the Cascadian Couloir, in particular Summit Post.org. One item to note, as it was our first time up and over Long's Pass, we missed the cairn that marks the route down, which is about 20 feet to the left of where the trail reaches the top of the pass. There are trails that g" - BryHong8, Sep 19, 2015
"As soon as we got closer to Stuart, the rain began to taper off, to our pleasure. As we pulled in the Stuart parking lot, we could see a group of 30 teenage girls assembled at the far end, all with backpacking gear. I was shocked. Were they ALL doing Stuart? Not being from the area, we didn’t know there was anything else around. Stuart is known for having lots of loose rock, which would be a hazard with that many people on the route. Turns out it was just a religious retreat and they were going to a nearby lake. Phew. The approach supposedly gained about 2000 feet, then lost over 1200 (suc" - justinraphaelson, Jul 28, 2015
"A true, definitional Grepic. This huge day had Grim obstacles but also Epic rewards. We left Seattle at midnight (wha?) and found ourselves hiking up to Long’s Pass before 3am. Up on the pass the wind gusts were fierce as we witnessed early dawn at 4:15. Soon we were ascending the climber’s path and the long loose dirt and rock gully up into the Cascadian Couloir. The couloir was snow-free the entire way up and tedious going on loose talus, scree, and dirt; a snow climb would have made it so much easier. We hit snow shortly after gaining the ridge slopes above the Crapcadian. All was " - scott, Jun 10, 2015
