In the Antarctic, the Allen Rocks (77°33′S 169°9′E / 77.550°S 169.150°E / -77.550; 169.150) are a small but distinctive group of rocks 2.2 nautical miles (4.1 km) east-northeast of Slattery Peak in the Kyle Hills on Ross Island. The feature includes a central nunatak that in outline resembles the letter 'A'. A low ridge encloses the nunatak except on the south. The group was named by the Advisory Committee on Antarctic Names in 2000 after Robert J. Allen of the U.S. Antarctic Resource Center, United States Geological Survey (USGS), Reston, Virginia, a cartographer and expert on aerial photography of Antarctica, who was closely involved in USGS mapping of the continent, 1950–2000.^[1]
