The Ames Range is northwest of the Mount Bursey massif in the Flood Range, from which it is separated by Forrest Pass, and southeast of the Berry Glacier and Demas Range. Glaciers draining the range include Coleman Glacier and Rosenberg Glacier on the west side, Jacoby Glacier on the east side and Herbst Glacier to the north. Peaks include Mount Andrus, Mount Boenninghausen, Mount Kosciusco and Mount Kauffman. Other features include Lind Ridge, Gardiner Ridge and Brown Valley.

## Discovery and naming

The Ames Range was discovered by the United States Antarctic Service (USAS; 1939–41) and named by Richard E. Byrd for his father-in-law, Joseph Ames.

## Geology

The Ames Range consists of three coalescing shield volcanoes: Mount Andrus, Mount Kosciusko and Mount Kauffman, and Mount Boennighausen. The north slopes of the range are in the west of the Usas Escarpment.
