There’s a tiny glacier clinging to the side of Wheeler Peak in Great Basin National Park in western Nevada. Once upon a time, the Wheeler Peak Glacier was so massive it carved the mountain into its current shape, but now it only measures 300 by 400 feet. The National Parks Service estimates that if temperatures continue to rise, the glacier will disappear entirely in as few as 20 years. Flickr user brewbooks took a few pictures of the glacier from a 2009 hike up to the summit. See more images in his album on Flickr.
