The first ascent of Mount Jackson was made by a team led by John Crabbe Cunningham of the British Antarctic Survey (BAS) in 1964.

Supraglacial moraines on the mountain's east side measure between 1–5 kilometres (0.62–3.11 mi) in length and display boulders at their distal ends.

The first topographic mapping of Mount Jackson was carried out in November 1940 by a sledge party of the United States Antarctic Service (USAS).

[13] The northern part of the mountain system, which extends over 1,590 kilometres (990 mi), covers most of the Antarctic Peninsula, and Mount Jackson is its highest peak.

Supraglacial moraines on the mountain's east side measure between 1–5 kilometres (0.62–3.11 mi) in length and display boulders at their distal ends.

The prominent mountain 3 nautical miles (5.6 km; 3.5 mi) north-northwest of Mount Jackson, at the east side of the Dyer Plateau.

A conspicuous nunatak, largely snow covered, located 5 nautical miles (9.3 km; 5.8 mi) southwest of Mount Jackson.

It rises above the ice surface 6 nautical miles (11 km; 6.9 mi) east-southeast of the summit of Mount Jackson.

Named by the US-ACAN for Brent L. Davis, USARP biologist at Palmer Station, 1971, and in the Antarctic Peninsula area, 1974-75 season.
