[2] The dominant topography is tall, steep-sided ridges, trending north-south, with peak elevations spanning 1000 to 1200 m.[3] The range consists of the Fosdick Metamorphic Rocks[3] of migmatite gneiss and granite.

The peak is named in recognition of Bruce P. Luyendyk, professor (emeritus), University of California, Santa Barbara, who was active in ground- and ocean-based Antarctic research from 1989 to 2015, significantly advancing the scientific knowledge of the Ross Embayment region of Antarctica.

A rock peak 860 metres (2,820 ft) high 2 nautical miles (3.7 km; 2.3 mi) southwest of Mount Iphigene.

Discovered in December 1929 by the ByrdAE and named for Henry G. Avers, chief mathematician of the Division of Geodesy, United States Coast and Geodetic Survey.

A prominent northerly projection from the main massif of the Fosdick Mountains 4 nautical miles (7.4 km; 4.6 mi) northeast of Mount Avers.

Named for Ernest E. Lockhart, physiologist at West Base of the USAS and a member of the biological party which visited this area in 1940.

A rock bluff on the north side of the Fosdick Mountains, 2.5 nautical miles (4.6 km; 2.9 mi) east of Mount Colombo.

Named by US-ACAN for Commander Charles F. Bird, Meteorological Officer on the Staff of the United States Naval Support Force, Antarctica, 1968.

A small but conspicuous nunatak 1 nautical mile (1.9 km; 1.2 mi) west of Mount Perkins.

Named for Jack E. Perkins, biologist at the USAS West Base (1939-41) and the leader of a biological party which visited this area in December 1940.

Named for George F. Getz, Jr., who, like his father, gave financial support toward the exploration efforts of Admiral Byrd.

A rock bluff on the south side of the Fosdick Mountains, 2 nautical miles (3.7 km; 2.3 mi) west of Mount Richardson.

Named for Doctor Charles J. Demas who provided medical assistance and supplies for the ByrdAE (1933-35) and USAS (1939–41).

A peak just west of Reece Pass and 3 nautical miles (5.6 km; 3.5 mi) south of Mount Colombo in the southeast part of the Fosdick Mountains.

Discovered on aerial flights made from West Base of the USAS (1939-41) and visited by a biological party in 1940.

A nunatak, badly sculptured away by ice, the remnant of a huge cone of an extinct volcano, located 2 nautical miles (3.7 km; 2.3 mi) southeast of Mount Richardson.

Discovered on 28 November 1934 by Paul Siple and Stevenson Corey of the ByrdAE, 1933-35, who investigated the feature and referred to it as "The Volcano."
