Info from Licensor: "This is Aialik Glacier that’s in the Kenai Fjords National Park. We went on a 7 1/2 hour glacier cruise with Major Marine Tours. We probably sat there about 10 minutes before it started to crash down. It seemed like slow motion. It calved for almost a full minute. The captain said she hadn’t seen the glacier calve that much at one time before."
