On May 28, 2008, Adam LeWinter and Jeff Orlowski filmed the “calving” of the Ilulissat Glacier in western Greenland. The chunk of ice that broke off was three miles wide, a mile deep and 3,000 feet high, with 300 to 400 feet above water and the rest below water. The separation from the main glacier took 75 minutes. It was the largest “calving” of a glacier ever captured on film. The film won the Excellence in Cinematography award at the 2012 Sundance Film Festival, and many other awards.
