Glaciers and Ice Formations

Accumulations and flows of glacial ice and the ice-built formations shaped by them, following the glacial landform class of standard geomorphology. Includes valley and mountain glaciers still actively flowing (Mendenhall Glacier, Columbia Glacier, Deming Glacier), large ice caps and ice sheets covering a whole region (East Antarctic Ice Sheet), and named ice tongues and icefalls where a glacier meets open water or breaks over a steep drop (Drygalski Ice Tongue). Belongs here: any formation whose defining identity is a present-day body of glacial ice. Does not belong here: a valley or fjord shaped by past glacial action that no longer carries ice (Valleys, Coastal and Reef Features), or a rock formation left standing by glacial retreat (Interfluves and Ridges, Other Erosional Landforms).
