Margerie Glacier, Glacier Bay National Park, Alaska – Image 2521

Margerie Glacier calves a massive iceberg from its face. Glaciers are constantly moving forward. This forward motion forces large chucks of ice to fall off the front or face of the glacier in what is known as glacier calving. I shot this photo while on a small boat cruise traveling through Southeast Alaska. This image illustrates page 94 in my new book on Alaska called Alaska: A Photographic Excursion and is also the photo for the month of February in my 2008 Southeast Alaska Calendar. Camera: Nikon F/5, Lens: 80-200mm f/2.8 Nikkor, Film 35mm Velvia slide film-Mark Kelley
