A crewmember on the Sea Shepherd in Antarctica captured this unusual sequence of images a couple years ago. “I literally raised my camera to my eye (Canon 1D Mark II w/70-200/2.8L lens), and the arch collapsed. I mashed the shutter button down and captured 20 frames—in bursts. I shot in bursts because I was afraid that the buffer wouldn’t hold.” He put it together those shots in this 9-second clip of the iceberg arch’s collapse. Antarctica is the world’s last great wilderness—come see it for yourself.
