Mount Southern () is a small mountain, or nunatak, located 1.5 nautical miles (2.8 km) northeast of Mount Harry and 14 nautical miles (26 km) southeast of FitzGerald Bluffs, in Palmer Land. Discovered and photographed by Lincoln Ellsworth on November 23, 1935. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1961–66.

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...
