Lemah Mountain is a mountain peak in the Snoqualmie Crest, a part of the North Cascades Mountains, of the Washington state. It is located approximately from the city of Snoqualmie Pass. Most noted for its five distinct summits, its name, Lemah, comes from the Chinook Jargon word Lemah, in turn derived from a French word, le main, meaning hand. Lemah Mountain formed by rocks crumpled into mountains by the Cascadia subduction zone where the Juan de Fuca and North American plates meet.
