Discovery and name edit
The Argentina Range was discovered and photographed on January 13, 1956, in the course of a United States Navy transcontinental nonstop plane flight from McMurdo Sound to Weddell Sea and return. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after Argentina, which for many years from 1955 maintained a scientific station on the Filchner Ice Shelf at the General Belgrano or Ellsworth Station site. The entire Pensacola Mountains were mapped by United States Geological Survey (1863) in 1967 and 1968 from ground surveys and from United States Navy tricameral photographs taken in 1964.[1]
Location edit
The Argentina Range lies between the Support Force Glacier to the west, which separates it from the Forrestal Range, and the East Antarctic Ice Sheet to the east.[2] The Blackwall Ice Stream joins the Recovery Glacier between the Argentina Range and Whichaway Nunataks.[3] The range is bisected by the San Martín Glacier, which flows west between the Schneider Hills to the south and the Panzarini Hills to the north. Features of the Schneider Hills include, from south to north, Pujato Bluff, Ruthven Bluff, Sosa Bluff and Lisignoli Bluff. Features of the Panzarini Hills include, from south to north, Vaca Nunatak, Mount Ferrara, Giro Nunatak, Suarez Nunatak, Arcondo Nunatak, Areta Rock and Mount Spann.[2]
