The Ilulissat Glacier in western Greenland produced the largest calving ever caught on video on May 28, 2008. Adam LeWinter and Jeff Orlowski were there, filming the changes in the glacier. What you see is pretty epic, but when they try to give us some scale, you realize it was even bigger than you imagined. The calving went on for 75 minutes, so this is a highlight reel, which became part of the award-winning film Chasing Ice. -via a comment at reddit
