  • 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).
