Marguerite Bay
In 1928–1930 and 1933–1935, Admiral Richard E. Byrd led two privately sponsored expeditions, one that included the first flight over the South Pole in 1929, sparking U.S. interest in Antarctica. The U.S. Antarctic Service Expedition (1939–1940), under the leadership of the U.S. Navy, maintained bases at Marguerite Bay and Bay of Whales.
