Urstromtal (Glaciology 🗻)
An urstromtal is a type of broad glacial valley, for example, in northern Central Europe, that appeared during the ice ages, or individual glacial periods of an ice age, at the edge of the Scandinavian ice sheet and was formed by meltwaters that flowed more or less parallel to the ice margin. Urstromtäler are an element of the glacial series. The term is German and means "ancient st...
Crevasse (Glaciology 🗻)
A crevasse is a deep crack that forms in a glacier or ice sheet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces.
Flute (glacial) (Glaciology 🗻)
Glacial flutes, also known as glacial fluting, are low, narrow, elongate, straight, parallel ridges that range between several centimeters to a few meters both in width and height. This glacial landform generally consist of glacial till, but sometimes either sand or silt and clay. They form subglacially and are orientated parallel to the direction of glacier flow. The...

Sandy Glacier Caves (Glaciology 🗻)
The Sandy Glacier Caves are a system of glacier caves within the ice of Sandy Glacier on Mount Hood, Oregon. They are thought to be the largest glacier caves in the lower 48 states of the United States. Surveys done in 2011 and 2012 have measured the system at over 1 mile in length or about 7,000 feet. The caves formed from internal...

Glaciokarst (Karst 🌍)
Glaciokarst is a geological term that refers to a specific type of karst landscape that been influenced significantly by past glacial activity. Karst landscapes consist of distinctive surface and subsurface landforms. These landforms are a result from dissolution of soluble rocks like limestone, gypsum or dolomite by water. In the c...
