While these photos did not appear in the production of Standby Snow, reality does set a backdrop. Above: two of the most venerable landmarks in Glacier National Park—Grinnell Glacier and Jackson Glacier. The top photo show the extent of Grinnell in 1910 and where it was after years of melting in 2017. Photo of Grinnell in 1910 taken by Morton Elrod; photo in 2017 courtesy Lisa McKeon/USGS.
