Natural Dock For Icebreaker -- The Coast Guard's icebreaker Eastwind rests In a natural dock of ice in Baffin Bay while crew members attempt to satisfy an urge to build an Eskimo igloo out of blocks of ice. The Eastwind waited In the ice while dog teams carried members of a hydrographic mission to the ice-bound Baffin Island in the Canadian Northwest Territories last summer. The Eastwind was blocked by ice too heavy for it to break through 25 miles from the Baffin Island shoreline. December 29, 1952. (Photo by U.S. Coast Guard Photo).
