Dec. 14, 1911. South Pole.

Norwegian explorer Roald Amundsen and his team are the first people to reach the South Pole, arriving a full month ahead of a rival British expedition led by Capt. Robert Falcon Scott.

Amundsen left his base camp at the Bay of Whales on the shore of the Ross Sea on Oct. 20, 1911, and started his 830-mile trek to the pole.

Scott, who left in November, reached the pole Jan. 17, 1912. He perished in March 1912 during the return trip a short distance from his base camp.
