Mefjell Mountain is a large mountain rising to 3,080 metres (10,100 ft), standing 5 nautical miles (9 km) west of Mount Bergersen in the Sør Rondane Mountains of Antarctica. It was mapped by Norwegian cartographers in 1946 from air photos taken by the Lars Christensen Expedition, 1936–37, and in 1957 from air photos taken by U.S. Navy Operation Highjump, 1946–47. It was named "Mefjell" (middle mountain) by the Norwegians because of its central location in the mountain group. [1]
A mountain is a large landform that rises above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges.

It was mapped by Norwegian cartographers in 1946 from air photos taken by the Lars Christensen Expedition, 1936–37, and named for Ambassador Birger Bergersen, chairman of the Norwegian Whaling Board. It was remapped in 1957 by the Norwegians from air photos taken by USN Operation Highjump, 1946-47.

Fjellimellom Valley is an ice-filled valley between Jutulsessen Mountain and Nupskammen Ridge in the Gjelsvik Mountains of Queen Maud Land, Antarctica. It was photographed from the air by the Third German Antarctic Expedition (1938–39). It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52), and from air photos by the Norwegian expedition (1958–59) and named Fjellimellom.
Gjel Glacier is a glacier, 17 nautical miles (31 km) long, flowing north between the steep cliffs of the Luncke Range and Mefjell Mountain, in the Sør Rondane Mountains of Antarctica.

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.
The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
