Ho-lee-crap. You're looking at the largest iceberg calving ever recorded — a whopping 7.4 cubic km (that's 1.77 mi3) hunk of ice, detaching itself from Greenland's Ilulissat glacier — captured by filmmaker James Balog. It's just one of the scenes in Balog's forthcoming film Chasing Ice, and it is remarkable to behold.
Oh, and in case you were wondering, this iceberg could be classified as "very large." Yes, that is the official nomenclature.
