Rainbow Glacier

Rainbow Glacier is an alpine glacier located in Glacier National Park, situated between 8000 and 8500 feet in elevation. The ice field displays prominent crevasses and fractures across its surface that mark the movement of ice downslope.

The glacier has diminished in size since the mid-1900s, reflecting the impact of warming temperatures across the region. This retreat is part of broader changes affecting ice fields throughout the northern Rocky Mountains.

Scientists regularly conduct field studies at Rainbow Glacier to measure mass balance, crevasse depth, and surface elevation for climate research.

Summer months provide the best conditions for visiting, as designated hiking trails throughout the park are generally snow-free and accessible. Visitors should prepare for high elevation with proper footwear and bring plenty of water for the journey.

Nearby geothermal vents release steam that creates an unusual visual contrast against the surrounding ice and snow. This rare meeting of heat and cold makes the area geographically distinct from other glaciers in the park.
