Coleman Glacier

Coleman Glacier lies on Mount Baker’s west slopes in Washington’s North Cascades, between Roosevelt Glacier and Heliotrope Ridge. It was named for Edmund Thomas Coleman, who belonged to the first mountaineering party to climb Mount Baker in 1868. Its modern history mirrors wider glacier change in the region: from 1850 to 1950 it retreated about 8,200 feet, then during a cooler, wetter period from 1950 to 1979 it advanced roughly 2,480 feet, before retreating again by 1,443 feet between 1980 and 2006. These changes make it a clear example of how sensitive Mount Baker’s ice is to shifts in climate.
