[3] The Reid Mountains are a group of arêtes extending south from the 200 to 400 metres (660 to 1,310 ft) high escarpment along the southern edge of the Shotton Snowfield.

The mountains are mostly made up of schists and gneisses, but Mount Wegener and the ridges east are topped with slates.

[6] Named features of the escarpment north of the range are, from west to east:[3] A rock spur (80°38′S 24°26′W / 80.633°S 24.433°W / -80.633; -24.433) rising to c. 1,500 metres (4,900 ft) and bounded by screes (taluses), located northwest of Arkell Cirque on the north side of the Read Mountains, Shackleton Range.

The formation is over 1,500 metres (4,900 ft) thick and is mainly composed of slates, with minor quartzites and some pebble conglomerates.

It overlays the Middle Precambrian Shackleton Range Metamorphic Complex of gneisses, schists and amphibolites.

[9] A group of nunataks (80°38′S 23°20′W / 80.633°S 23.333°W / -80.633; -23.333) 6 miles (9.7 km) north-north-east of Mount Wegener, rising to 1,470 metres (4,820 ft) near the east end of the Read Mountains, Shackleton Range.

In association with the names of geologists grouped in this area, named by the UK-APC in 1971 after Paul Niggli (1888-1953), Swiss geologist who introduced the cataloguing of magma types by molecular or Niggli values; Professor of Geology, University of Zurich.

Named by the UK-APC after William J. Arkell (1904–58), English geologist; specialist in Jurassic stratigraphy and paleontology.

In association with the names of geologists grouped in this area, named by the UK-APC in 1971 after Charles Lapworth (1842-1920), British geologist who established the stratigraphic succession in south Scotland and who defined the Ordovician system; Professor of Geology and Physiography, Birmingham University, 1881–1913.

[17] A cirque (80°44′S 22°48′W / 80.733°S 22.800°W / -80.733; -22.800) at the west side of Trueman Terraces in the east portion of the Read Mountains, Shackleton Range.

[19] A needle-shaped peak (80°44′S 24°59′W / 80.733°S 24.983°W / -80.733; -24.983) rising to 1,450 metres (4,760 ft)) at the southwest end of the ridge east of Glen Glacier, in the Read Mountains, Shackleton Range.

[20] Rock summit (80°43′S 24°47′W / 80.717°S 24.783°W / -80.717; -24.783) rising to 1,790 metres (5,870 ft) in the central part of the Read Mountains, in the Shackleton Range.

[14] Peak (80°40′S 24°40′W / 80.667°S 24.667°W / -80.667; -24.667) rising to 1,875 metres (6,152 ft), the highest elevation in the Read Mountains, Shackleton Range.

[22] Rock crags (80°44′S 24°05′W / 80.733°S 24.083°W / -80.733; -24.083) rising to c. 1,300 metres (4,300 ft) to the south of Arkell Cirque in the Read Mountains, Shackleton Range.

In association with the names of geologists grouped in this area, named by the UK-APC in 1971 after William Nicol (c. 1768-1851), Scottish natural philosopher who devised the Nicol prism and the preparation of thin rock sections, thus contributing to the techniques of microscopy.

Named by the UK-APC in association with the names of geologists grouped in this area after Alfred L. Wegener (1880-1930), German astronomer, meteorologist, and Arctic explorer; a pioneer of the theory of continental drift; Professor of Geophysics and Meteorology, University of Graz, Austria, 1924-30; Leader of German expeditions to Greenland in 1929 and 1930, losing life on the ice cap in November of that year.

The formation is over 2,500 metres (8,200 ft) thick, and overlays the Middle Precambrian Shackleton Range Metamorphic Complex of gneisses, schists and amphibolites.

In association with the names of geologists grouped in this area, named by the UK-APC after Sir Arthur E. Trueman (1895-1956), British geologist, who worked on the coal measures and their correlation by marine bands, and on the introduction of statistical methods into paleontology; Professor of Geology, Glasgow University, 1937-46; President, Geological Society of London, 1945–47.

[24] A flat-topped ridge (80°43′S 22°28′W / 80.717°S 22.467°W / -80.717; -22.467) rising to c. 1,500 metres (4,900 ft) and marking the east end of the Read Mountains, Shackleton Range.

In association with the names of geologists grouped in this area, named by the UK-APC after Henry Hurd Swinnerton (1876–1966), British zoologist and paleontologist, Professor of Geology, University College of Nottingham (later Nottingham University), 1912–46; President, Geological Society, 1938–40.

First seen from the air and examined from the ground by the CTAE in 1957, and so named because of the recovery of the expedition's vehicles which repeatedly broke into bridged crevasses on this glacier during the early stages of the crossing of Antarctica.
