The Downshire Cliffs (71°37′S 170°36′E) are a line of precipitous basalt cliffs rising to 2,000 metres (6,600 ft) above the Ross Sea and forming much of the east side of Adare Peninsula along the coast of Victoria Land. In 1841 Captain James Clark Ross applied the name "Cape Downshire" to a part of these cliffs. He did so at the request of Commander Francis R.M. Crozier of the Downshire. No prominent cape exists here and, for the sake of historical continuity, the name has been reapplied to these cliffs.
