Lightning Peak

Just west of Lake Cushman, the route follows the Copper Creek trail, moderate snow or talus slopes, then a ridge rock scramble to the summit. This is a moderate scramble of 7 miles and 3,800 feet of elevation gain.

Approach & Ascent

From the trailhead on Forest Road 2451, follow Copper Creek Trail for 2.2 miles, gaining 2,400 feet, to a saddle on the north ridge at 3,200 ft.  From here follow the ridge south on a way trail for a half mile to a basin with a prominent gully.  This basin can be avalanche-prone in winter and early spring. Rather than ascending the gully, scramble on snow or talus, and bearing southeast up slopes to the Timber-Lightning ridge at 4,000 ft.  Once on the ridge-top, scramble west up and down about 1/4 mile to the true summit at 4,654 ft.
