Largest Glacier-Calving Ever Filmed....it makes the glacier calving we're seen in Alaska look miniscule. On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 1 km, 100 to 150 meters above water and the rest below water. "CHASING ICE" captures largest glacier calving ever filmed
