The Elfin Cove DEM covers the community of Elfin Cove, which is a census-designated place (CDP) near the northwestern corner of Chichagof Island in Hoonah-Angoon Census Area, in the panhandle of southeast Alaska. The DEM has a 1/3 arc-second (~10 meter) cell size, and is referenced to a vertical datum of mean high water. It was built in March 2011 to support NOAA's Tsunami Program.
