Tidewater terminus of a glacier (name unknown) in the far southwest of Greenland.  Note the pool of gray-brown water adjacent to the center of the calving front.  This may be the site of fresh water upwelling, where subglacial water drains down the bed of the glacier, then emerges from beneath the ice at the calving front.  This fresh water is less dense than the seawater in the fjord, so it immediately rises to the surface, carrying rock dust from the bed with it, and creating the striking color contrast.
