I was able to catch the moment of maximum force as an enormous slab of ice broke loose from the face of this glacier and plunged two hundred feet into the water. We saw the ice begin to move, slide, and hit, and only then did the sound reach us – a shattering blast that sounded like an exploding bomb. Notice the background of blue ice behind the blast – we can see smaller chunks of ice in free fall within the detail. This entire process is called “calving.”
