      • The Thomas Hills (84°21′S 65°12′W) are a linear group of hills, 17 nautical miles (31 km; 20 mi) long, between Foundation Ice Stream and MacNamara Glacier at the north end of the Patuxent Range in the Pensacola Mountains, Antarctica.


      Exploration and name


      The Thomas Hills were mapped by the United States Geological Survey (USGS) from surveys and from United States Navy air photos, 1956–66.
      They were named by the United States Advisory Committee on Antarctic Names (US-ACAN) at the suggestion of Captain Finn Ronne, United States Navy Reserve, leader at Ellsworth Station, 1957.
      Charles S. Thomas was United States Secretary of the Navy, 1954–57, during the first few years of United States Navy Operation Deep Freeze.


      Location




      The Thomas Hills run in a northeast direction between the Foundation Ice Stream and the MacNamara Glacier. They parallel the Anderson Hills on the south side of the MacNamara Glacier.
      Features, from west to east, include Mount Yarbrough, Nance Ridge, Martin Peak and Mount Warnke.
