Butler Rocks

The Butler Rocks are two rock nunataks, 910 metres (3,000 ft) high, standing 2.5 nautical miles (5 km) southwest of Vanguard Nunatak in the northern Forrestal Range, Pensacola Mountains. They were mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1956–66, and named by the Advisory Committee on Antarctic Names for William A. Butler, aerographer, Ellsworth Station winter party, 1957.[1]
