Pelton Peak is a 7,133-foot summit in Washington’s North Cascades National Park, near Cascade Pass and the Ptarmigan Traverse, in rugged terrain molded by uplift and repeated Pleistocene glaciation. Yawning Glacier lies on its western flank, and runoff from the mountain feeds tributaries of the Stehekin River. The peak’s name preserves the mining history of the surrounding basin country, recalling the Pelton wheel used in early mining operations near Pelton Basin, Horseshoe Basin, and Boston Basin. The mountain also lies in a marine west coast climate zone, where Pacific storms bring heavy precipitation and winter snow, while summer more often brings clearer skies.
