The Welch Mountains are near the Black Coast of central Palmer Land, which borders the Weddell Sea to the east. They are west-southwest of Lehrke Inlet, west-northwest of the Kvinge Peninsula, north of Mount Jackson, east of the Dyer Plateau and south of the Eland Mountains.

## Discovery and name

The Welch Mountains were probably seen from the air by Lincoln Ellsworth in 1935 and their north extremities were sketched in 1936 by a British Graham Land Expedition (BGLE) sledge party under John Rymill. In 1940 they were photographed from the air and charted from the ground by the United States Antarctic Service (USAS), and in the expedition reports and charts were assumed to be Ellsworth's Eternity Range. They were mapped in detail by United States Geological Survey (USGS) in 1974. Named by The United States Advisory Committee on Antarctic Names (US-ACAN) for Rear Admiral David F. Welch, Commander, United States Naval Support Force, Antarctica, 1969–71.
