The mountains were probably among those viewed by Admiral Byrd and other members of the USAS in plane flights from the ship Bear on Feb. 24 and 25, 1940. They were mapped in the course of the 1957-58 oversnow traverse from Byrd Station to the Sentinel Range led by Charles R. Bentley, and named after Albert P. Crary, who was then Deputy Chief Scientist for the US-IGY Antarctic Program.
