Features

Geographical features and nearby features include:

Mount Weir

. A steep section of the polar plateau escarpment with almost all of the rock exposed facing northeast, standing just south of the base of Fulgham Ridge at the head of Ramsey Glacier. Discovered and photographed by United States Navy Operation Highjump on Flight 8A of Feb. 16, 1947, and named by United States Advisory Committee on Antarctic Names (US-ACAN) for Maj. Robert R. Weir, United States Marine Corps, pilot of this flight.

Mount Cromie

. A snow-covered mountain, high, rising southeast of Mount Boyd in the Bush Mountains. Discovered and photographed by the United States Antarctic Service, 1939-41. Surveyed by A.P. Crary, leader of the United States Ross Ice Shelf Traverse Party (1957-58), and named by him for William Cromie, assistant glaciologist with the party.

Mount Boyd

. A pyramidal mountain, high, standing west of Mount Bennett, in the Bush Mountains. Discovered and photographed by the United States Antarctic Service, 1939-41. Surveyed by A.P. Crary, leader of the United States Ross Ice Shelf Traverse Party (1957-58), and named by him for Walter Boyd, Jr., glaciologist with the party.

Mount Bennett

. A prominent mountain, high, about east of Mount Boyd, surmounting the west part of Anderson Heights, Queen Maud Mountains. Discovered by the United States Antarctic Service (1939-41), and surveyed by the United States Ross Ice Shelf Traverse Party (1957-58) led by A.P. Crary. Named by Crary for Hugh Bennett, seismologist with the party.

Cascade Bluff

. A low, mainly ice-covered bluff that forms the southwest wall of Mincey Glacier in the Queen Maud Mountains. The feature was so named by the Texas Tech-Shackleton Glacier Party, 1962-63, because water cascades over the bluff during warm periods.
