Key:glacier:type

The glacier:type key is used to provide additional information about the morphology and classification of a glacier tagged with natural=glacier. For the specific conventions of mapping glaciers and land ice in the Antarctic see also Antarctica/Tagging.

Values

The following values are in active use, for more proposed values see Proposed features/Glaciers tags

Values for glacier:type=*
value	definition	example	image	Taginfo
glacier:type=icecap	Ice masses, dome shaped, with radial flow, raising above the surrounding terrain, see Wikipedia	The Vatnajökull glacier
glacier:type=icefield	Ice masses significantly covering underlying topography but constrained by mountains (in contrast to ice caps which lie on top of them), see Wikipedia	The Southern Patagonian Ice Field
glacier:type=valley	Valley glaciers are glaciers at the bottom of a single valley flowing downward	The Mer de Glace in the Mont Blanc massif
glacier:type=mountain	All smaller glaciers that do not fill a whole valley	The Tré-les-Eaux glacier
glacier:type=rock	Flowing ice masses not originating from snow usually containing significant amounts of soil/rocks Using this tag for  Rock glaciers /  Blockgletscher is controversial because rock glaciers are unique landforms that are not the same as "true" ice glaciers. Many existing rock glaciers are mapped using natural=scree. Consider using geological=rock_glacier as a secondary tag to identify these features.	Active rock glacier, Lange-Wand-Kar, Zillertal Alps, Tux main ridge
glacier:type=shelf	Ice shelves are larger areas of thick, permanent glacier ice floating on the ocean	The Ross ice shelf
glacier:type=ice_tongue	A long and narrow sheet of ice projecting out from the end of a tidewater glacier over water	The Erebus ice tongue, Antarctica
