The Yee Nunataks (74°22′S 72°30′W) are a group of scattered nunataks, about 24 nautical miles (44 km; 28 mi) long and 12 nautical miles (22 km; 14 mi) wide, centered 35 nautical miles (65 km; 40 mi) northeast of Lyon Nunataks in Ellsworth Land, Antarctica.
The nunataks rise 1,300–1,700 metres (4,300–5,600 ft) in elevation and in the four quadrants include Staack Nunatak, Olander Nunatak, Metzgar Nunatak and Triassic Nunatak.
Location
The Yee Nunataks are in eastern Ellsworth Land, to the south of the English Coast of George VI Sound.
They are north of the Lyon Nunataks, Merrick Mountains and Sky-Hi Nunataks.
Individual nunataks include, from west to east, Staack Nunatak, Horner Nunatak, Tollefson Nunatak and Olander Nunatak.
Mapping and name
The Yee Nunataks were mapped by the United States Geological Survey (USGS) from surveys and United States Navy aerial photographs, 1961–68, and United States Landsat imagery, 1973–74.
They were named in 1994 by United States Advisory Committee on Antarctic Names (US-ACAN) after Virginia Yee-Wray, cartographer and air brush specialist in the Shaded Relief and Special Maps Unit, Branch of Special Maps, USGS, who for many years prepared USGS shaded relief maps of Antarctica.
