|Paleo Slide Set: The Ice Ages|
|Glacier in East Coast Mountains of Baffin Island, Nunavut, Canada.|
Tucked amongst the jagged peaks of the Canadian Arctic lies a glacier, a slow moving river of ice that flows downhill through the valley at speeds of several meters per year. Glacial ice is
formed by the accumulation, compression, and re-crystallization of many years' snowfall at high altitudes or latitudes where temperatures are not sufficient to melt all the winter's snow accumulation. Glaciers come in all shapes and sizes, including
this small mountain glacier found in the East Coast Mountains of Baffin Island in north-central Canada.
