Discovery and name
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.
