Climbing the Southeast Face via Echo Lake
From Bishop, take Highway 168 west about 18 miles to the Lake Sabrina trailhead, with overnight parking near the North Lake turnoff. Follow the Sabrina Basin Trail past Blue and Dingleberry Lakes toward Hungry Packer Lake, then go cross-country by Moonlight Lake into the Echo Lake drainage and the cirque between Haeckel and Wallace. Climb loose talus on the southeast side to the summit rocks, where a narrow chute and Class 3 moves finish the climb. Helmets help on the loose rock. Many parties camp near Echo Lake and add Wallace, using an Inyo National Forest wilderness permit reserved up to six months ahead.
