Lot 5967-4:  Aerial view of the Pettiwick Glacier, Greenland.  The wall of ice at that point was about 200 feet high, and this image shows a panoramic view of about 5 miles.   The ice divided by the crevasses will break off later and float away with the tide and currents.  Some of the larger bergs will find their way down into the North Atlantic ocean shipping lanes after drifting for many months down Baffin Bay and Davis Strait.  The Coast Guard helicopter from U.S. Coast Guard icebreaker Eastwind (WAGB-279) took this photograph.   Official U.S. Coast Guard Photograph, release September 1952.  Photographed through Mylar sleeve.  (2015/10/09).   Note, the Chicago Tribune has a photograph online which claims copyright on this image.   They do not have copyright as it is U.S. Coast Guard photograph.
