Columbia Glacier, Alpine glacier in Henry M. Jackson Wilderness, Washington, United States.

Columbia Glacier lies in the Henry M. Jackson Wilderness of Washington, descending from 5,600 ft to 4,700 ft above sea level. It is surrounded by Columbia Peak, Monte Cristo Peak and Kyes Peak, and its meltwater feeds Blanca Lake and Troublesome Creek, a tributary of the North Fork Skykomish River.

Columbia Glacier lost 278 ft (85 m) of length between 1979 and 2004. Researchers attribute the retreat to reduced winter snowpack and increased summer melting, which produced a negative mass balance. They describe the ice as out of equilibrium with the climate, so it is expected to keep thinning and retreating.

The glacier feeds Blanca Lake and Troublesome Creek, a tributary of the North Fork Skykomish River, so its meltwater reaches the Skykomish drainage. It lies within the Henry M. Jackson Wilderness, where hikers cross the surrounding peaks of Columbia Peak, Monte Cristo Peak and Kyes Peak. The name Columbia is shared with the peak above it.

Access is available via hiking trails in Mount Baker-Snoqualmie National Forest, best during warmer months when snow is lower. The routes require moderate fitness and standard mountain gear for steep terrain.

The glacier feeds both Blanca Lake and Troublesome Creek, a tributary of the North Fork Skykomish River. Between 1979 and 2004 it retreated 278 ft (85 m), a loss attributed to reduced winter snowpack and stronger summer melting, leaving it out of balance with the climate.
