Mapping and name edit

The Iroquois Plateau was mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photographs in 1956–66. It was named by the United States Advisory Committee on Antarctic Names after the Bell UH-1 Iroquois helicopter which has greatly facilitated field operations in Antarctica.[1]

Location edit

 
Northern part of the Neptune Range

The Iroquois Plateau is in the Neptune Range.[2] It is east of the Washington Escarpment and south of the Median Snowfield. Scattered nunataks on the plateau include Elmers Nunatak, Ferrell Nunatak, Hill Nunatak and the Edge Rocks.[3]

Hill Nunatak edit

84°00′S 54°45′W / 84.000°S 54.750°W / -84.000; -54.750.
