Timelapse films are edging dangerously close to becoming passé. But then one comes along like the fascinating bit above, filmed in at Ilulissat Icefjord, Greenland. The Sermeq Kujalleq glacier at the head of the fjord calves magnificent icebergs that drift toward open sea 70 kilometers away. At the mouth of the fjord, the icebergs encounter a shallow bank where they stack up and strand themselves, some several hundred feet tall. And the icebergs keep coming. The glacier calves them at an astonishing rate—as many as 40-50 cubic kilometers of ice break off each year.
