Derrick Peak

Derrick Peak (-80.06667°N, 156.38333°W) is a prominent ice-free peak, 2,070 m high, overlooking the south side of Hatherton Glacier, 3 nmi west of the north end of Johnstone Ridge.

Name
Derrick Peak was named by the Advisory Committee on Antarctic Names for Robert O. Derrick of the United States Weather Bureau, who served as assistant to the United States Antarctic Research Program Representative at Christchurch from 1960 until his death in 1966.

Location
Derrick Peak is in the north of the Britannia Range, overlooking the Hatherton Glacier to the north, which forms the boundary with the Darwin Mountains. It is east of a line of relatively ice-free valleys and ridges along the south side of Hatherton Glacier, north of Mount Henderson and west of Johnstone Ridge and Dusky Ridge. Most of the nearby features were named in association with Britannia by a University of Waikato (New Zealand) geological party, 1978-79, led by M.J. Selby.
