This is a primordial ice lake formed by the relentless August sun melting the surface of the ice in Greenland. These lakes are created in a just a few hours and can be 2 km wide and 35 meters deep. When the water becomes too heavy the entire body disappears in a matter of seconds! The ice cracks and the water flushes to the bottom of the glacier were it provides the lubricant that causes the glacier flow off the continent. I took this image of a co-host walking on the edge of the lake when were setting up to shoot a sequence that would involve the first ever boat ride filmed on a lake like this.
