Sperry Glacier, Alpine glacier in Glacier National Park, Montana
The glacier extends across the northern slopes of Gunsight Mountain, featuring steep ice formations and multiple glacial streams flowing into surrounding valleys.
Professor Lyman B. Sperry led an expedition in 1895 to map this region, resulting in the glacier receiving its current name.
Scientists monitor the glacier yearly to document climate impacts, as it has decreased from 930 acres to 216 acres between the 1850s and 2005.
Visitors reach the glacier through a 7-mile round trip hike from Sperry Chalet, climbing 1,600 feet across rocky terrain and snow fields.
The glacier produces mineral-rich meltwater that flows into surrounding lakes, creating a distinctive milky blue color from suspended rock particles.
