In 2007 photojournalist James Balog, who shot the image featured in the magazine's August photo spread ("Lakes on Ice," by Sid Perkins), gathered a team of scientists, photographers and filmmakers to launch the Extreme Ice Survey. The project, one of the most ambitious photographic glacial surveys ever undertaken, documents changes in the ice formations using dozens of time-lapse cameras placed at 18 sites around the world, including Greenland, Iceland and the Nepalese Himalayas. The photos in this slide show come from the forthcoming book Ice: Portraits of Vanishing Glaciers (Rizzoli, September 2012), by Balog and the Extreme Ice Survey team.
