Thomas Hills (Antarctica)

The Thomas Hills (84°21′S 65°12′W) are a linear group of hills, 17 miles (27 km) long, between Foundation Ice Stream and MacNamara Glacier at the north end of the Patuxent Range in the Pensacola Mountains, Antarctica. They were mapped by the U.S. Geological Survey from surveys and from U.S. Navy air photos, 1956–66. The hills were named by the Advisory Committee on Antarctic Names at the suggestion of Captain Finn Ronne, U.S. Navy Reserve, leader at Ellsworth Station, 1957. Charles S. Thomas was Secretary of the Navy, 1954–57, during the first few years of U.S. Navy Operation Deep Freeze.
