Snake Ridge (84°49′S 66°30′W / 84.817°S 66.500°W / -84.817; -66.500 (Snake Ridge)) is a serpentine ridge, 4 nautical miles (7.4 km; 4.6 mi) long, adjoining the northwest extremity of Mackin Table in the Patuxent Range, Pensacola Mountains.[1]

Exploration and name

[edit]

Snake Ridge was mapped by United States Geological Survey (USGS) from surveys and United States Navy air photos in 1956–66. The descriptive name was proposed by Dwight L. Schmidt, USGS geologist to these mountains, 1962–66.

Location

[edit]
Snake Ridge to east of center

Snake Ridge is just west of the northwest end of Mackin Table, to the east of Mount Weininger. A number of nunataks are scattered in the ice-covered terrain to the south, west and north, including Brooks Nunatak, Brazitis Nunatak, Postel Nunatak, DesRoches Nunataks, DeWitt Nunatak, Lawrence Nunatak, Natani Nunatak and White Nunataks.[2]
