Exploration and name
editThe 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.[1]
Location
editThe 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.[2]
