Mattox Bastion

Mattox Bastion (77°38′S 160°56′E) is one of the peaks of the Inland Forts in the Asgard Range, Victoria Land, Antarctica. Flory Cirque sits on its southwest slopes, on the north side of Taylor Glacier, between a pair of rock spurs named West Groin and East Groin.[1][2] West Groin separates Flory Cirque from Mudrey Cirque.[3]

West Groin was the first of these features to be named; it was named by the British Antarctic Expedition of 1910–13, led by Captain Robert F. Scott.[3] Mattox Bastion, Flory Cirque and East Groin were named later, by the Advisory Committee on Antarctic Names.[1][2][4] Mattox Bastion was named for Commander Benjamin G. Mattox, U.S. Navy, officer-in-charge of the Naval Support Force winter-over detachment at McMurdo Station in 1971.[1] East Groin was named in reference to West Groin, and Flory Cirque was named for Robert F. Flory, a United States Antarctic Research Program geologist at McMurdo Station for three seasons, 1968–71.[2][4]
