Benson Bluff

Benson Bluff (80°0′S 157°57′E) is a distinctive triangular rock bluff in Antarctica, about 1,300 metres (4,300 ft) high, at the west side of Ragotzkie Icefall in the Britannia Range. It was named by the Advisory Committee on Antarctic Names after Dale P. Benson, United States Geological Survey cartographer who conducted surveys at South Pole Station, 1993–94, and supported the first airborne GPS controlled photogrammetry project, which established photo control on Black Island and positioned the location of seismographic equipment on the flanks of Mount Erebus.
