The Allegheny Mountains ( 77°15′S143°18′W / 77.250°S 143.300°W ) are a small group of mountains 10 nautical miles (19 km; 12 mi) west of the Clark Mountains in the Ford Ranges of Marie Byrd Land, Antarctica. [1]
The Allegheny Mountains are north of the upper Boyd Glacier and the Mackay Mountains, east of the Sarnoff Mountains and west of the Clark Mountains. Features, from west to east, include Mount Darling, Mount Spencer, Mount Tolley, Mount Swartley, Mount Zeigler and Cady Nunatak. Isolated features to the north and east include the Mathis Nunataks, Spaulding Rocks and Breeding Nunatak. [2]
The Allegheny Mountains were discovered on aerial exploration flights in 1934 by the Byrd Antarctic Expedition (ByrdAE) and subsequently mapped from aerial flights and ground surveys by the United States Antarctic Service (USAS) from 1939 to 1941. They were named by the USAS for Allegheny College, Meadville, Pennsylvania which is the alma mater of Paul Siple, leader of the United States Antarctic Service West Base. [1]

The Alexandra Mountains are a group of low, separated mountains in the north portion of Edward VII Peninsula, just southwest of Sulzberger Bay in Marie Byrd Land, Antarctica.
The Wisconsin Range is a major mountain range of the Horlick Mountains in Antarctica, comprising the Wisconsin Plateau and numerous glaciers, ridges and peaks bounded by the Reedy Glacier, Shimizu Ice Stream, Horlick Ice Stream and the interior ice plateau.
