Ruth Glacier’s Great Gorge is quite simply one of the continent’s most awe-inspiring sights. At 2000 feet and over 10 miles long, it’s one of the deepest canyons in the world.

Ruth Glacier is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. Its upper reaches are approximately 3 vertical miles below the summit of Denali. The glacier’s “Great Gorge” is one mile wide, and drops almost 2,000 feet over 10 miles, with crevasses along the surface.
