Most lakes in the world occupy basins scoured out by glaciers. Glacial motion can be fast (up to 30 metres per day (98 ft/d), observed on Jakobshavn Isbræ in Greenland) [1] or slow (0.5 metres per year (20 in/year) on small glaciers or in the center of ice sheets), but is typically around 25 centimetres per day (9.8 in/d).

The Extreme Ice Survey (EIS), based in Boulder, Colorado, uses time-lapse photography, conventional photography and video to document the effects of global warming on glacial ice. It is the most wide-ranging glacier study ever conducted using ground-based, real-time photography.
Glaciers are melting faster, losing 31% more snow and ice per year than they did 15 years earlier, according to three-dimensional satellite measurements of all the world’s mountain glaciers.
An ice stream is a region of fast-moving ice within an ice sheet. It is a type of glacier , a body of ice that moves under its own weight. [ 2 ] They can move upwards of 1,000 metres (3,300 ft) a year, and can be up to 50 kilometres (31 mi) in width, and hundreds of kilometers in length. [ 3 ]
Satellite images show the world’s glaciers are melting faster than ever, with more than half the melt coming from the U.S. and Canada, according to a new study.

The Columbia Glacier, a glacier in Prince William Sound on the south coast of the U.S. state of Alaska, is one of the fastest moving glaciers in the world, and has been retreating since the early 1980s. It was named after Columbia University, one of several glaciers in the area named for elite U.S. colleges by the Harriman Alaska Expedition in ...
Several glaciers flow into the Shimshal Valley, and are prone to blocking the river. Khurdopin glacier surged in 2016–17, creating a sizable lake. [2] Glaciers of Shimsal Valley from space, May 13, 2017. Khurdopin glacier has dammed the Shimshal River, forming a glacial lake. The river has started to carve a path through the toe of the glacier.
