Ruth Glacier

Ruth Glacier is a glacier in Denali National Park that stretches through the Alaska Range and is surrounded by towering granite walls. The ice reaches depths of several thousand feet in places, making it one of the most substantial frozen masses in the region.

The glacier was named in 1903 by explorer Frederick Cook, who discovered it during his expedition through the Denali region. Cook chose the name of his youngest daughter, connecting this geographic location to his family.

The distinctive granite peaks flanking the glacier carry names like Moose's Tooth and Bear Tooth, reflecting how local culture connects the landscape to wildlife. Visitors flying over the ice surface can see these shapes and understand how the region interprets its natural features.

Visitors can only reach this location through authorized air services that operate from designated landing areas within the park. It is important to book in advance, as weather conditions in this mountainous area often affect flights.

The ice mass constantly moves, shifting several feet each day as it descends toward the valley below. This continuous motion makes it a living landscape feature that transforms over time and shows visitors something different each visit.
