The 1911 photo shows Grinnell Glacier poised at the top of the waterfalls in the foreground and joined with what is now called Salamander Glacier in the background. Grinnell described this wall of ice as being 1,000 feet high in 1887. As of 2008, that wall of ice is gone and Grinnell Glacier is not even visible in the contemporary photograph. Instead, it is behind the buff-colored ridge just above the waterfalls. Salamander Glacier lies along the Garden Wall below the ridgeline. This glacier is thinning in the middle so rapidly that it will probably be in two pieces within a few years. To the upper left is the small, rounded glacier, Gem Glacier, that until recently had not shown signs of retreat. It, too, is now becoming smaller (with kind permission of http://nrmsc.usgs.gov/repeatphoto).
