The range is surrounded by, and largely covered by, an ice sheet. Only the peaks are visible.

Discovery

The range was first seen by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) on the evening of 4 January 1930 as a mirage on the horizon. The peaks of the Masson Range and Casey Range were also visible in the mirage. On 14 February 1931 the range was mapped from the Discovery. Sir Douglas Mawson, named the range for Professor Edgeworth David of the BANZARE committee.

The David Range () is 5 mi west of the Masson Range, which it parallels, in the Framnes Mountains of Antarctica. It extends 16 mi in a north-northeast–south-southwest direction. The range is about 11 km south of Holme Bay. The range lies to the southwest of Mawson Station. The northern tip of the range is nearly 10 km due west of the northern tip of the Masson Range. The Brown Range (or Sortindane Peaks) is to the south and the Casey Range to the east. The highest point is the peak of Mount Elliot, at about 1300 m.

Appearance

According to the 1960 Sailing Directions for Antarctica

Geology

The Framnes Mountains have elevations up to 1500 m above sea level, and rise up to 400 m above the ice surface. They have dark, weathered charnockite bedrock that is littered with light-colored quartz-rich, granitic gneiss glacial erratics. The erratics cover the lower slopes of the David Range and Mount Hordern, but are not found more than about 250 m above the present-day ice surface. Above this level the darker charnockite bedrock is exposed. Probably the boulders were transported from the south and deposited by ice during the last glacial maximum, while the exposed bedrock would have remained above the ice.

Glaciation

The East Antarctic Ice Sheet (EAIS) formed about 34 million years ago, and seems to have persisted since then with periodic fluctuations in thickness between glacial and inter-glacial cycles. During the last glacial cycle the ice sheet thickened more near the coast, less further inland. This is shown by the upper limit of glacial erratic boulders, ranging from 820 m on Fang Peak near the sea in the north of David Range, to 860 m on Mount Elliot, 1100 m on Mount Coates and 1300 m on Mount Hordern, which is about 30 km from the sea. The ice surface appears have lowered by several hundred meters during the present interglacial.

Today the range has a number of small mountain glaciers. The David and Masson ranges divide the ice flow in the Framnes Mountains into three outlet glacial streams. Ice surface velocities of 21 m per year have been measured in the ice stream to the east of the David Range, and 31 m per year in the ice stream to the west. In the period between January and September 1956 ice in the plateau near the range moved up to 36 ft.

Fang Peak

In 1959 J C Armstrong, surveyor at Mawson Station, used the peak as an unoccupied trigonometrical station. In January 2023 a team from the Mawson Mountaineering Club climbed the peak.

Mount Elliot

Mount Lawrence
