. It is bounded to the east by the Pearl Harbor Glacier, Muller Glacier, Lensen Glacier and Wood Glacier.


Features

Features include, from northwest to southeast,


Inferno Peak

. A peak north of Le Couteur Peak in the north end of Millen Range. So named by the Southern Party of NZFMCAE, 1962-63, because geologic examination showed it contained the granite/greywacke contact, with baking of the sedimentary rock imparting a reddish color to the peak.


Head Peak

. A peak east of Le Couteur Peak, situated on a projecting ridge of Millen Range in the névé area of Pearl Harbor Glacier. So named by the Southern Party of NZFMCAE, 1962-63, due to its likeness to a head and to its position at the head of Pearl Harbor Glacier.


Omega Peak

. A peak northeast of Le Couteur Peak. So named by the Southern Party of NZFMCAE, 1962-63, because this was the last major peak climbed by the party, January 2, 1963.


Le Couteur Peak

. A peak between Cirque and Omega Peaks, in the north part of Millen Range. Named by the Southern Party of the NZFMCAE, 1962-63, for P.C. Le Couteur, geologist with this party.


Cirque Peak

. A peak south of Le Couteur Peak. So named by the Northern Party of NZFMCAE, 1962-63, due to the peak's position at the head of a large
cirque A (; from the Latin word ) is an amphitheatre-like valley formed by Glacier#Erosion, glacial erosion. Alternative names for this landform are corrie (from , meaning a pot or cauldron) and ; ). A cirque may also be a similarly shaped landform a ...

névé Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow can contribute to glacier formation through the process of ''nivation''. Névé that survives a ...

Gless Peak

. A peak, high, standing west-southwest of Cirque Peak. Mapped by the

(US-ACAN) for Elmer E. Gless, biologist at Hallett Station, summers 1965-66, 1966-67 and 1967-68.


New Year Peak

. The major peak about high on the northwest side of Toboggan Gap. The name was suggested by Bradley Field, geologist, NZGS, whose field party camped below the peak during the New Year period, 1981-82.


Toboggan Gap

. A pass through the Millen Range just north of Turret Peak, offering good sledging from the polar plateau to the Pearl Harbor Glacier ne~ve. Named by the Southern Party of NZFMCAE, 1962-63.


Turret Ridge

. A ridge about long extending northeast from Turret Peak. Visited by a New Zealand Antarctic Research Programme (NZARP) geological party led by R.H. Findlay, 1981-82, and named in association with Turret Peak.


Turret Peak

. A prominent rock peak, high, standing northwest of Crosscut Peak. The peak is topped with a high vertical spire, or tower, which is an excellent landmark. Named for its distinctive appearance by the Southern party of NZFMCAE, 1962-63.


Crosscut Peak

. A peak, high, just north of Joice Icefall. So named by the Southern Party of NZFMCAE, 1962-63, due to its jagged northern ridge and summit.


Joice Icefall

. An icefall draining from the polar plateau through the Millen Range into Lensen Glacier. Named by the Southern Party of NZFMCAE, 1962-63, after I. Joice, field assistant to the party.


Mount Aorangi

. The highest mountain, high, in the Millen Range. So named by the NZFMCAE, 1962-63, because of this mountain's cloudpiercing ability, and also in memory of Mount Cook, New Zealand, known to the Maori people as "Aorangi" (the cloud piercer).


Braddock Peak

. A peak rising to high immediately southeast of Mount Aorangi in the south part of Millen Range. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC), on the proposal of geologist R.A. Cooper, after Peter Braddock, field leader of geological parties to the area in the 1974-75 and 1980-81 seasons.


Mount Pearson

. A prominent snow peak high situated at the west side of the mouth of Lensen Glacier where the latter joins Pearl Harbor Glacier. Named by the northern party of NZFMCAE, 1962-63, for F.H. Pearson, surveyor with the party.
