The Irish word was and is used particularly to describe long sinuous ridges, which are now known to be deposits of fluvio-glacial material. The best-known example of such an eiscir is the Eiscir Riada , which runs nearly the whole width of Ireland from Dublin to Galway , a distance of 200 km (120 mi), and is still closely followed by the main ...
Ruth Glacier is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. [1] 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 (610 m) over 10 miles (16 km), with crevasses along the surface.

Surprise Glacier is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. The glacier begins in the Alaska Range near Mount Dall, moving west. Its terminus is the source of the Tonzona River. [1] [2] [3]
Muldrow Glacier, also known as McKinley Glacier, is a large glacier in Denali National Park and Preserve in the U.S. state of Alaska. Native names for the glacier include, Henteel No' Loo' and Henteel No' Loot. [1] The glacier originates from the Great Icefall of Harper Glacier on the eastern side of Denali.
Thousands of users, some on commercial cruises and others on private trips, travel on the river each year. The proximity of the Denali Highway, which runs parallel to the upper river for about 15 miles (24 km), and the Parks Highway, which follows the river for 80 miles (130 km), makes the river accessible at many places.

The Moose's Tooth (or simply Moose's Tooth, Mooses Tooth) is a rock peak on the east side of the Ruth Gorge in the Central Alaska Range, 15 miles (24 km) southeast of Denali. Despite its relatively low elevation, it is a difficult climb.
The valley wall prevents meltwater streams from flowing outward away from the glacial snout. Instead, glacial meltwater is diverted laterally along the ice margin and deposits sediments between the glacier and valley wall. [25] As the glacier retreats, the process may repeat creating a stepped slope or terrace referred to as a kame terrace.
