Boulder Glacier, Alpine glacier on Mount Baker, Washington, United States
Boulder Glacier extends from the summit crater between Grant Peak and Sherman Peak down to 5,000 feet elevation on Mount Baker's southeast slope.
Between 1850 and 1950, the glacier experienced substantial retreat, losing 8,700 feet of length before advancing again due to cooler weather conditions.
The glacier serves as a research location for scientists studying climate patterns and environmental changes in the Cascade Range mountain system.
Visitors can reach Boulder Glacier through Boulder Ridge Trail number 605, which passes through forests of Pacific silver fir trees.
The glacier generates recurring geothermally induced debris avalanches, with six documented incidents since 1958 originating from Sherman Peak.
