Hubbard Glacier calving. (To purchase prints or downloads, click on the "Buy" or shopping cart button above the image.) This is the longest tidewater glacier in Alaska, and its open calving face is over ten kilometers (6 miles) wide. The face rises an average of about 200 meters (600 feet) above the water (Disenchantment Bay). The ice chuck that just fell and produced this splash was over 100 meters (300 feet) high, or the height of a 25-story building. The glacier routinely calves off icebergs the size of a ten-story building.
