The Polar Geospatial Center's Arctic DEM at 2 m resolution covering most of the arctic including Alaska

below example: the Muldrow Glacier in Denali National Park

21.0-1.0 ka timeslice of ice-sheet limits for North America (Dyke, 2004)

Note: in Alaska, the glacier extents are depicted as the larger expansions of the early Wisconsin rather than the smaller late Wisconsin limits that are documented in this atlas.

update coming soon available here
