The clearest name is valley glacier, because what defines one is that it occupies a valley in the mountains. (It is the mountains that should be called alpinethat is, jagged and bare due to glaciation.) Valley glaciers are what we typically think of as glaciers: a thick body of solid ice that flows like a very slow river under its own weight. Pictured is Bucher Glacier, an outlet glacier of the Juneau Icefield
in southeastern Alaska. The dark stripes on the ice are medial moraines
, and the wavelike forms along the center are called ogives.
