Prydz Bay
Bluff Island is an island lying south of Magnetic Island and west of the Breidnes Peninsula, Vestfold Hills, in Prydz Bay, Antarctica. It was mapped from aerial photos taken by the Lars Christensen Expedition, 1936–37, re-emapped by the Australian National Antarctic Research Expeditions (1957–58) and so named because the south end of the island is marked by a steep cliff face.
