Grinnell Glacier basin in Glacier National Park, Montana includes three glaciers: Gem Glacier (perched on the Continental Divide), Salamander Glacier (once connected to Grinnell) and Grinnell Glacier itself. Upper Grinnell Lake is the turqouise blue lake that has been created by the melting of the glacier. The creamy blue color of the lake is indicative of an active glacier. Glacier flour, the fine sediment created by the grinding action of the movement of the ice, is suspended in the water column of the lake, causing the spectacular color.
This photo was taken from the summit of Angel Wing mountain. The USGS Climate Change in Mountain Ecosystems project intends to repeat this photo from the same location each year to track changes in the glacier. Grinnell Glacier has become an iconic symbol of climate change because of the many images that exemplify the glacier's sensitivity to the warming climate.
