North Pole Expedition 1968

Ralph Plaisted, suburban St. Paul, Minn. insurance man, points to the spot north of Baffin Bay which will serve as base camp in his second drive to reach the North Pole via snowmobile, Feb. 21, 1968 in Minneapolis. Plaisted's party, which left for Canada today, was forced to turn back last year when the polar ice began to break up. (AP Photo/Robert Walsh)
