Detroit Plateau (64°10′S60°0′W) is a major interior plateau of Graham Land, with heights between 1,500 and 1,900 metres (4,900 and 6,200 ft). Its northeast limit is marked by the south wall of Russell West Glacier, from which it extends some 90 miles (140 km) in a general southwest direction to Herbert Plateau. The plateau was observed from the air by Sir Hubert Wilkins on a flight of December 20, 1928. Wilkins named it Detroit Aviation Society Plateau after the society which aided in the organizing of his expedition but the shortened form of the original name is approved.
