The Jones Mountains lie to the south of the Eights Coast, south of the Abbot Ice Shelf and southeast of Thurston Island. Features of the southern part include, from west to east, Miller Crag, Sutley Peak, Walk Glacier, Forbidden Rocks and Christoffersen Heights. Features of the northern part include, from west to east, Pillsbury Tower, Bonnabeau Dome, Cache Heights, Inspiration Rocks, Gopher Glacier, Anderson Dome and Mount Loweth.

## Discovery and naming

The charts of the United States Antarctic Service (USAS), 1939–41, show mountains in this approximate location and relationship to Dustin and Thurston Islands, indicating they were sighted in the flight from the ship Bear, February 27, 1940. The mountains appear in distant air photos taken by United States Navy Operation Highjump, December 30, 1946, and were observed from United States Navy aircraft by Edward Thiel and J. Campbell Craddock on January 22, 1960. The naming was proposed by Thiel and Craddock after Dr. Thomas O. Jones (1908–93), American chemist; senior National Science Foundation (NSF) official in charge of the United States Antarctic Research Program (USARP), 1958–78; Director, Division of Environmental Science, NSF, 1965–69; Deputy Assistant Director for National and International Programs, NSF, 1969–78.
