Colorado-based photographer-adventurer James Balog, of the Extreme Ice Survey, is working on a new series of time-lapse images of the ice and glaciers on Mount Everest. Slate obtained exclusive use of some of the earliest images from the project, including a video of the Khumbu Icefall, one of the most dramatic areas of glacial change over the past 50 years. The movement of glaciers is subtle to the human eye. But with time-lapse photography, Balog can compress nine months into 10 seconds and make glacial change patently visible.
