Ingraham Glacier

Ingraham Glacier is an active glacier on Mount Rainier's southeastern flank, flowing eastward between prominent rock features toward lower glacier systems. The ice flows gradually downslope from the summit plateau in this heavily traveled mountaineering corridor.

The glacier was named after Edward Sturgis Ingraham, an early explorer of Mount Rainier who documented the peak's features. During the last ice age roughly 35,000 years ago, the glacier was part of a much larger ice system that extended far down the mountain.

The glacier bears the name of Edward Sturgis Ingraham, who dedicated significant time to exploring and documenting Mount Rainier's natural features.

Visitors require a permit from Mount Rainier National Park to access the glacier and typically start from Camp Muir. The route across the adjacent glacier involves ice travel and demands proper mountaineering skills and equipment.

In June 1981, one of the worst mountaineering disasters in American history occurred here when an ice collapse killed eleven climbers. The tragedy highlighted the severe hazards climbers face in this remote alpine setting.
