The tag glacier:part=* describes a part of a glacier where some attributes are different from the rest of the glacier. Polygons with glacier:part=* should either be within a separate natural=glacier area representing the entire glacier or - in case of the Antarctic - within the implicitly mapped ice sheet. The purpose of this tag is similar to that of building:part=*.
How to map
To map a small part of a glacier with distinct properties you can just draw a line closing on itself along the outline of the area and tag it glacier:part=*. To map large glaciers you can use Relation:multipolygon with the same tag.
Outside the Antarctic the glacier:part=* polygon should be located within a polygon representing the glacier as a whole tagged natural=glacier.

| glacier:part=moraine | Part of a glacier or icesheet covered by scree from rockfall from surrounding rock faces, which is transported with the moving glacier, often in form of a medial moraine. See Moraine. Useful combinations are geological=moraine and surface=scree.

|
||
| glacier:part=icefall | Steep and strongly crevassed section of a glacier. See Icefall
|
|
||
| glacier:part=crevassed | General crevassed section of a glacier without the crevasses individually being mapped with natural=crevasse | 
|

| glacier:part=yes | Unspecified glacier part with properties defined by other tags | |||
