Harrison Glacier

Harrison Glacier is an alpine glacier in Glacier National Park sitting on the southeast-facing ridge south of Mount Jackson. The ice field spreads across the high mountain slopes at an elevation where few other features can survive.

The glacier formed during the ice age and has shifted back and forth across the landscape over thousands of years. In recent decades it has fared better than most others in the park.

The glacier functions as a natural laboratory for scientists studying climate patterns and glacial movements in the northern Rocky Mountains.

The glacier is reachable on foot through mountain trails that require solid hiking experience and stamina. Weather conditions change rapidly at this elevation so proper gear makes a real difference.

As the largest remaining glacier in Glacier National Park, Harrison Glacier maintains its mass due to its high-altitude position above 2,700 meters.
