Jones Mountains
The Jones Mountains are an isolated group of mountains, trending generally east–west for, situated on the Eights Coast, Ellsworth Land, Antarctica, about south of Dustin Island.
Location
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, 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, American chemist; senior National Science Foundation official in charge of the United States Antarctic Research Program, 1958–78; Director, Division of Environmental Science, NSF, 1965–69; Deputy Assistant Director for National and International Programs, NSF, 1969–78.

Forbidden Rocks
.Linear rock outcrops, long, located on the west edge of Christoffersen Heights and between Haskell and Walk Glaciers.
Mapped by the University of Minnesota–Jones Mountains Party, 1960-61.
So named by the party because the rocks were inaccessible from their northwest approach because of crevasse fields.

Northwest features
Snowplume Peak
.A small pyramidal peak along the north front of the Jones Mountains, located west-southwest of Rightangle Peak and west-southwest of Pillsbury Tower.
Mapped by the University of Minnesota-Jones Mountains Party, 1960-61.
So named by the party because a continual plume of wind-blown snow trails off the peak whenever the wind blows.
Rightangle Peak
.A small rock peak between Snowplume Peak and Camelback Ridge.
Mapped by the University of Minnesota-Jones Mountains Party, 1960-61.

Avalanche Ridge
.A linear rock ridge, long, extending north from Pillsbury Tower

Greenstone Point
.High rock spur along the north front of the Jones Mountains, immediately east of Austin Valley.
Mapped by the University of Minnesota-Jones Mountains Party, 1960-61.
So named by the party because of the greenish color of the rock.
Hughes Point
.Steep rock point on the west side of the terminus of Exum Glacier.
