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 7.7 miles (12.4 km) 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, like all of the Cascade Range, is approximately 15,000 years old, formed by rocks crumpled into mountains by the Cascadia subduction zone where the Juan de Fuca and North American plates meet.
The mountain has five separate summits, the highest of which is more than 7,480 feet (2,280 m) above sea level. Lemah One (6,960'), Lemah Two (7,280'), Main Peak (7,512', also called Lemah Three), Lemah Four (7,200') and Lemah Five (7,040') make up these peaks. Each summit has an individual ascent path. Main Peak, the highest of the five towers, was first ascended in 1923.
The Lemah Glacier rests on the east slope of the mountain, and is mostly divided into three remaining sections. Lemah Creek, a stream named after the mountain, drains this glacier and eventually meets the Cooper River. Burnt Boot Creek drains another flank of Lemah Mountain, and it is a tributary of the Cooper River as well. On the western flank of Lemah is a small lake called Avalanche Lake.
- Lemah Mountain's main summit was first climbed by Wallace Burr and party on July 7, 1923.
- Lemah One (6960'), also called Lemah Thumb and Iapia Peak, was first climbed on the 1925 Mountaineer outing.
- On the eastern spur of Lemah Two, there stands two rock towers, the lower of which is the more massive. The upper tower (7000'), also known as Goatshead Spire, was first climbed on August 8, 1982 by Donald Goodman and John Mason.
