Colchuck Glacier is a small glacier in Washington’s Stuart Range, immediately north of Colchuck Peak and Dragontail Peak in the Alpine Lakes Wilderness of Wenatchee National Forest. Below it sits Colchuck Lake, which gave its name to the glacier and a nearby mountain. About 0.30 mile long and 0.10 mile wide at its broadest, the glacier drops from roughly 7,600 feet to about 6,400 feet and ends on barren rock and talus above the lake. Its name comes from Chinook Jargon, meaning “cold water” or “ice,” reflecting the stark high basin in the Cascades.
