Digital Elevation Models of Glacier Bay National Park, Between Lituya Bay and Icy Point, Alaska, Derived from Airborne Lidar Data Acquired in September 2015
This dataset provides four digital elevation models derived from airborne lidar data acquired over four separate areas along and adjacent to the Fairweather Fault along the remote Gulf of Alaska coast within Glacier Bay National Park. In 1958, the Fairweather Fault in southeast Alaska ruptured over...
