  • Approach-Deluge Lake Trailhead (8,700-ft) to Deluge Lake (11,700-ft)-3,000-ft
  • West Ridge & Southeast Face (11,700-ft) to summit (13,041-ft)-1,270-ft

    RT-9 miles
    Vertical Gain-4,311-ft

    Starting at the Deluge Lake TH, follow the obvious trail as it begins its relentless ascent up into the Deluge Lake Drainage. The first two miles will do 2350-ft of vertical gain! After two miles the trail will begin to moderate. Continue on this single-track trail as it makes its way to Deluge Lake. The last 1.63 miles to the lake will do only 770-ft of elevation gain.

    Route Description

    Once at Deluge Lake (11,745-ft), locate the steep, grassy or snow covered southeast slope of “Grand Traverse Peak.” Immediately hike around the east (left) side of the lake. From here hike up steep grass covered ledges (class 2) and either attain the east ridge or continue up the face. The standard and easiest route would be the east ridge. Once on the ridge, follow it to the summit. The route steepens considerably towards the summit.

    Essential Gear

    Expect snow up in the Deluge Basin until early June. Bring crampons and an ice axe for the moderately sloped southeast face.
