Columbia Glacier is a glacier located in the Henry M. Jackson Wilderness in the U.S. state of Washington. It descends from 5600feet to 4700feet above sea level. It is surrounded by Columbia Peak, Monte Cristo Peak, and Kyes Peak and is a source of water for Blanca Lake and Troublesome Creek, a tributary of the North Fork Skykomish River.
The glacier retreated 278feet between 1979 and 2004. The retreat is due to recent reduced winter snowpack and more summer melting leading to negative mass balance. The glacier is in disequilibrium with climate and will continue to thin and retreat.[2]
