Peck Range

. A range of mountains, ridges and hills, long north–south and wide, in the west part of Du Toit Mountains. The feature rises to about high and is bounded to the south by a high snowfield, and to the east and west by unnamed north-flowing glaciers that coalesce at the north end of the range, south of Mount Wever. The range was mapped by USGS from United States Navy aerial photographs taken 1966-69 and was visited by a USGS-BAS joint field party, 1986-87. In association with the names of geologists grouped in this area, named by US-ACAN in 1988 after Dallas Lynn Peck, geologist, a world authority on igneous rocks, including granites; eleventh director of the United States Geological Survey, 1981-93; previously, Chief Geologist of the Geologic Division, USGS. Bedrock in the range is almost entirely made up of a coarse-grained fresh granite batholith.

Mount Marquis

. A mountain in the south part of Du Toit Mountains, situated north of

, south-southwest of Dietz Bluff and due west of the north end of Pullen Island. It was mapped by USGS from United States Navy aerial photographs, 1966-69. Named by US-ACAN after Peter T. Marquis, general assistant, BAS, a member of the joint BAS-USGS party to this area, 1986-87.
