Crack Bluff (86°33′S 158°38′W) is a bluff 8 nautical miles (15 km) southeast of Kutschin Peak on the west side of the Nilsen Plateau in the Queen Maud Mountains. The bluff rises to 2,810 metres (9,220 ft) and has an extensive area of exposed rock. The name was proposed by Edmund Stump of the United States Antarctic Research Program Ohio State University field party which geologically mapped the bluff on December 27, 1970. It is descriptive of the peculiar subhorizontal crack containing breccia fragments exposed on the steep southwest face.
