Description Geomorphic, stratigraphic, geotechnical, and biogeographic evidence indicate that failure of a Pleistocene ice dam generated a megaflood from glacial Lake Atna down the Matanuska Valley in south-central Alaska. While it has long been recognized that Pleistocene Lake Atna occupied ≥9000 km2 of the Copper River Basin, little attention has focused on the lake’s discharge locations and behavior. Digital elevation model and geomorphic analyses suggest that progressive lowering of the lake level by...
