'Ruth Glacier' is a
glacier in
Denali National Park and Preserve in the
U.S. state of
Alaska.
[1] Its upper reaches are almost three vertical miles (4.8 km) below the summit of
Mount McKinley. The glacier's "Great Gorge" is one mile (1.6 km) wide, and drops almost 2,000 feet (600 m) over ten miles (16 km), with
crevasses along the surface. Above the surface on both sides are 5,000-foot (1,500-m)
granite cliffs. From the top of the cliffs to the bottom of the glacier is a height exceeding that of the
Grand Canyon. Ruth Glacier moves at a rate of 3.3 feet (1 m) a day and was measured to be 3,800 feet (1,158 m) thick in 1983.
[2]
Surrounding the Ruth Gorge are many mountains of the
Alaska Range, including the
Mooses Tooth, with highly technical
ice and
rock climbs on their faces.
