Lemah Mountain is a prominent peak in Washington’s Alpine Lakes Wilderness on the Snoqualmie Crest in the North Cascades, notable for five distinct summits rising from one mountain mass. Its name comes from Chinook Jargon derived from the French le main, meaning “hand,” reflecting those five tops. The highest summit, Main Peak, reaches 7,512 feet. First ascents came in the 1920s, and Goatshead Spire on Lemah Two’s eastern spur was first climbed in 1982. The mountain was formed by tectonic compression associated with the Cascadia subduction zone and later shaped by glaciation, with streams, a glacier, and Avalanche Lake surrounding it.
