Convoy Range

Convoy Range (76°47′S 160°45′E) is a broad mountain range in Antarctica. Much of the range has a nearly flat plateau-like summit, extending south from the Fry Saddle and ending at Mackay Glacier. The range has steep cliffs on its east side, but it slopes gently into the Cambridge Glacier on the western side.

The New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) worked in this area in 1957. The party named the range for the main convoy into McMurdo Sound in the 1956–57 season, with the names of the various vessels being used for features in the range.

Alatna Valley (76°53′S 161°10′E) (sometimes incorrectly spelled Atlanta Valley[1]) is an ice-free valley lying 4 miles (6 km) north of Mount Gran and trending east-northeast for about 10 miles (16 km) along the southeast side of the range.[2] It is one of the northernmost of the McMurdo Dry Valleys.[2] Parker Calkin, U.S. geologist, made stratigraphic studies in the valley during the 1960–1961 season.[2] Named by Advisory Committee on Antarctic Names in 1963 for the gasoline tanker USNS Alatna (T-AOG-81) which participated in Operation Deep Freeze 1958–1959 and 1959–1960, and in keeping with other ship names in the Convoy Range.[2]

Taff Y Bryn (76°43′S 161°25′E) is a ridgelike summit capped by dolerite (about 1,600 m), situated 1 nautical mile (1.9 km) west of Flagship Mountain in the Convoy Range. It is named after the River Taff in Wales, the toponym in Welsh literally means "Hill of the Taff." It was named by the 1976–77 Victoria University of Wellington Antarctic Expedition (VUWAE) led by Christopher J. Burgess.
