Nelson Peak (83°40′S 55°3′W / 83.667°S 55.050°W / -83.667; -55.050 (Nelson Peak)) is a 1,605 metres (5,266 ft) peak in Antarctica, standing at the eastern end of Drury Ridge and Brown Ridge where the two ridges abut Washington Escarpment, in the Neptune Range, Pensacola Mountains.[1]

Exploration and name

[edit]

Nelson Peak was mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photographs from 1956 to 1966. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Willis H. Nelson, a geologist with the Neptune Range field party of 1963–64.[1]

Location

[edit]
Northern part of the Neptune Range

Nelson Peak is towards the center of the Washington Escarpment, west of the Iroquois Plateau and east of the Roderick Valley. It is north of Mount Dover and south of Mount Moffat. The Drury Ridge extends west from Nelson Peak, separated by the Miller Valley from Brown Ridge, which extends north from the peak. Hannah Ridge is just north of Brown Ridge.[2]
