This new crack formed during the noisy lakebed breakup of two days ago. We know this because we hiked over this area a day before, and there wasn't a crack here. Now, there is a cleft right through the ice, starting well outside the lake basin and running straight through the center of the lake. Waterfalls pour melted water into the crack. We can hear it echoing as it bounces off the icy walls of the crack, into the depths.

Ian Joughin of the Polar Science Center Applied Physics Lab at the University of Washington (UW), examines a large, angular crack in the ice during a 2008 expedition to Greenland. A team of four scientists from the Woods Hole Oceanographic Institution and UW returned for their third year of study to better understand how Greenland's ice sheet is disappearing. Learn more about the expedition on the Polar Discovery web site.
