Multi-decadal Glacial Lake Inventory in the Alaska Region between 1984 and 2019
This dataset is an inventory of all lakes within 1 km (kilometer) of a glacier in Alaska and northwest Canada (Randolph Glacier Inventory (RGI) Region 01) for four different time periods: 1984-1988, 1997-2001, 2007-2011, and 2016-2019. Outlines were created from ~5-year Landsat composites made in Go...
