National Geographic : 1955 Apr
545 Gilbert Grosvenor 4' Alert Station Is Lost in Icy Wastes Almost invisible in the trackless landscape, Alert is one of five far-northern stations from which Canadian and U. S. civilians transmit vital weather observations (map, page 547). Mould Bay and Isachsen can be supplied only by air. Alert is com paratively accessible; icebreakers have reached it on three attempts, only the 1954 expedition failing. Dr. Gilbert Grosvenor, Chairman of the Board of the National Geographic Society, made this photo graph from the U. S. Air Force plane that took him to the North Pole in May, 1953 (page 557). Upended slabs of ice, some of them 20 feet high, form a pebbled pattern where the Arctic Ocean's pack ice grinds against the shore. The dark gash in the center is the land world's northernmost air strip. Buildings (arrow) appear as mere dots.
