Aufeis - Sheetlike mass of layered ice.

Galbraith Lake Aufeis


Aufeis (Owf - Ice) is German for "Ice on top". As rivers in extreme climates freeze, layers of ice build up.

Unlike lake ice, which will melt fairly regularly as the temperature rises in the summer, aufeis will remain in a large sheet above the running river as the snow and ice thaw. Since it is not sitting in the water, as a sheet of ice on a lake is, it takes much longer to warm up and melt. The snow and ice are very reflective, and while the water may be warming up to over 10 degrees C, the ice stays frozen. It makes for some cool temporary caves...
