Grinnell Glacier Overlook 1940 - 2013 Active

Grinnell Glacier taken from the Grinnell Glacier Overlook off the Highline Trail, Glacier National Park. The view of Grinnell Glacier taken circa 1940 shows the early formation of Upper Grinnell Lake, a proglacial lake visible at the terminus of the glacier. The 2013 photo shows a dramatic increase in the size of the lake as a result of melting ice.
