[[File:C79197s1 Ant.Map Carlyon Glacier Cook Southeast Massif.jpg|thumb|Southeast massif. Diamond Hill furthest south, below the long ridge of [[Brown Hills]].]]
The southeast massif extends southwest from Carlyon Glacier to Darwin Glacier. The Ross Ice Shelf is to the East. Feature, from south to north, are:

===Diamond Hill=== 
{{coord|79|52|S|159|09|E}}.
A conspicuous snow-free hill which is diamond shape in plan, standing {{convert|10|mi}} east of Bastion Hill at the north side of the lower Darwin Glacier.
Named by the Darwin Glacier Party of the CTAE (1956-58) which surveyed this area.{{sfn|Alberts|1995|p=187}}

===Brown Hills===
{{main|Brown Hills}}
{{coord|79|46|S|158|33|E}}.
A group of mainly snow-free hills in the Cook Mountains, lying north of the lower reaches of Darwin Glacier.
Named for their color by the Darwin Glacier Party of the [[Commonwealth Trans-Antarctic Expedition]] (CTAE) (1956-58).{{sfn|Alberts|1995|p=97}}

===Cooper Nunatak=== 
{{coord|79|45|S|159|11|E}}. 
A large rocky nunatak {{convert|5|mi}} north of Diamond Hill, protruding through the ice east of the Brown Hills.
Mapped by the VUWAE, 1962-63.
Named for R.A. Cooper, geologist with the VUWAE, 1960-61.{{sfn|Alberts|1995|p=151}}

===Dot Peak=== 
{{coord|79|46|S|159|10|E}}.
A small eminence, {{convert|1,450|m}}, marking the highest point of Cooper Nunatak, at the east side of the Brown Hills.
Mapped by the VUWAE (1962-63) and so named because of its small size.{{sfn|Alberts|1995|p=196}}

===Schoonmaker Ridge===
{{coord|79|39|S|158|50|E}}.
A jagged ridge, 4.5 nautical miles (8&nbsp;km) long, that runs east from the south part of [[Reeves Plateau]], Cook Mountains. Named by [[Advisory Committee on Antarctic Names]] (US-ACAN) after remote sensing scientist James W. (Bill) Schoonmaker, Jr., topographic engineer, [[United States Geological Survey]] (USGS). He spent three austral summers in Antarctica, 1972–76, with geodetic work at [[South Pole]], [[Byrd Station]], [[Antarctic Peninsula]], [[Ellsworth Mountains]] and [[Ross Ice Shelf]], where he determined the precise location of geophysical sites established during the Ross Ice Shelf Project, 1973-74 field season.{{sfn|Schoonmaker Ridge USGS}}

===Soyuz-13 Rock===
{{coord|79|40|S|159|8|E}}.
A [[nunatak]], {{convert|1270|m}} high, located 2 nautical miles (3.7&nbsp;km) southeast of Schoonmaker Ridge in the Cook Mountains.
Named after the Soviet spacecraft Soyuz 13 of December 18, 1973.{{sfn|Soyuz-13 Rock USGS}}

===Reeves Bluffs===
{{coord|79|36|S|158|40|E}}.
A line of east-facing rock bluffs, {{convert|8|mi}} long, situated {{convert|15|mi}} west of Cape Murray in the Cook Mountains.
Discovered by the BrNAE (1901-04) under Capt. Robert F. Scott, who gave the name "Mount Reeves," after Edward A. Reeves, Map Curator to the Royal Geographical Society, to a summit along this bluff. The bluff was mapped in detail by USGS from surveys and U.S. Navy aerial photography (1959-63). Since a prominent mountain does not rise from the bluffs, and because the name Mount Reeves is in use elsewhere in Antarctica, the US-ACAN (1965) recommended that the original name be amended and that the entire line of bluffs be designated as Reeves Bluffs. Not: Mount Reeves.{{sfn|Alberts|1995|p=610}}

===Cheney Bluff===
{{coord|79|39|S|159|48|E}}.
A steep rock bluff at the south side of the mouth of Carlyon Glacier, {{convert|5|mi}} southwest of Cape Murray.
Mapped by the USGS from tellurometer surveys and Navy air photos, 1959-63.
Named by US-AC AN for Lt. Cdr. D.J. Cheney, RNZN, commander of HMNZS Rotoiti on ocean station duty between Christchurch and McMurdo Sound, 1963-64.{{sfn|Alberts|1995|p=132}}

===Soyuz-18 Rock===
{{coord|79|39|S|159|25|E}}.
A distinctive [[nunatak]] 3 nautical miles (6&nbsp;km) west of Cheney Bluff in the Cook Mountains. The feature rises to {{convert|1230|m}} and is pyramid shaped, especially when viewed from the west. Named after the Soviet spacecraft Soyuz 18 of May 24, 1975.{{sfn|Soyuz-18 Rock USGS}}

===Fontaine Bluff===
{{coord|79|35|S|159|42|E}}.
Bluff {{convert|4|mi}} west of Cape Murray on the south side of Carlyon Glacier.
Mapped by the USGS from tellurometer surveys and Navy air photos, 1959-63.
Named by US-ACAN for Lt. Cdr. R.K. Fontaine, USN, commander of USS Hissem on ocean station duty in support of aircraft flights between Christchurch and McMurdo Sound, 1963-64.{{sfn|Alberts|1995|p=250}}
