Stephenson Bastion
Stephenson Bastion is a mountain massif with steep rock cliffs on its south side, rising to 1,850 m in the south-central part of Shackleton Range. It was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition, and it was photographed by U.S. Navy aircraft in 1967. It was named by the United Kingdom Antarctic Place-Names Committee for Philip J. Stephenson, an Australian geologist with the transpolar party of the CTAE in 1956–58.
