Glaciers

Glaciers are slowly-moving rivers of ice propelled forward by the stress of their own massive weight. A mass of land ice that is formed by the cumulative recrystallization of firn. A glacier flows slowly from an accumulation area to an ablation area. Some well-known glaciers are: the Zermatt, Stechelberg, Grinelwald, and Les Diablerets in Switzerland; the Nigards, Gaupne, Fanarak, and Lom in Norway; the Wright Taylor and Wilson Piedmont glaciers in Antarctica; Grinnell glacier in Glacier National Park, Montana, U.S., and the Teton glacier in Teton National Park, Wyoming, U.S.
