From Global Warming Art
A 1981 aerial photograph of Grinnell Glacier in Glacier National Park with indications of the approximate former extent of the glacier. This glacier has retreated from a total extent of ~2.3 square kilometers circa 1850 to ~1.1 square kilometers in 1993, and is now distributed in two major and five minor segments.  Like other glaciers in Glacier National Park, it is predicted that Grinnell Glacier will disappear by 2030 under current projections for the rate and extent of global warming (Hall 1994).
