The formation of 3 to 4 km (1.9 to 2.5 mi) thick ice sheets equate to a global sea level drop of about 120 m (390 ft) The Quaternary glaciation , also known as the Pleistocene glaciation , is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing.
The glacier is in the Lewis Range and rests on the north flank of Mount Gould at an altitude averaging 7,000 feet (2,100 m), in the Many Glacier region of the park. [3] The glacier has been one of the most photographed glaciers in the park and many of these photographs date back to the mid 19th century during the late Little Ice Age. When ...
The WAIS is bounded by the Ross Ice Shelf, the Ronne Ice Shelf, and outlet glaciers that drain into the Amundsen Sea. Dakshin Gangotri Glacier, a small outlet glacier of the Antarctic ice sheet, receded at an average rate of 0.7 m (2.3 ft) per year from 1983 to 2002. On the Antarctic Peninsula, which is the only section of Antarctica that ...
A glacier stream is a channelized area that is formed by a glacier in which liquid water accumulates and flows. [1] Glacial streams are also commonly referred to as "glacier stream" or/and "glacial meltwater stream". The movement of the water is influenced and directed by gravity and the melting of ice. [1]

Collective name for the morphologic structures in/on/under/around a glacier. Moraine Accumulated debris that has been carried by a glacier and deposited at its sides (lateral moraine) or at its foot (terminal moraine). Névé Area at the top of a glacier (often a cirque) where snow accumulates and feeds the glacier. Nunatak/Rognon/Glacial Island
Cornelius Krieghoff's 1847 painting The Ice Bridge at Longue-Pointe. An ice bridge is a frozen natural structure formed over seas, bays, rivers or lake surfaces. They facilitate migration of animals or people over a water body that was previously uncrossable by terrestrial animals, including humans.
Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
