Ahern Glacier

Ahern Glacier is a glacier in Glacier National Park that stretches between two mountain peaks at elevations ranging from 8,800 to 8,000 feet. The ice formation sits east of the Continental Divide and creates a distinctive feature in this alpine terrain.

This glacier was named after George Patrick Ahern, a Lieutenant Colonel in the United States Army. The National Park Service assigned the name as part of mapping the protected park lands.

Scientists regularly monitor this glacier to study climate patterns and environmental changes within the protected lands of Glacier National Park.

Hiking trails in the park offer different ways to view this glacier, with clearer visibility during the warm months from July to September. It helps to check trail conditions before visiting and prepare for significant elevation gain.

This glacier feeds a dramatic waterfall that plunges over 500 meters in a single drop into the crystal lake far below. Witnessing this cascade is a remarkable experience for visitors who find the right viewpoint.
