The Tombaugh Cliffs are ice-free rock cliffs on the east coast of the West Antarctic Alexander I Island . They rise up on the northern flank of the confluence of the Pluto Glacier in the George VI Sound .
Aerial photographs were taken during the American Ronne Antarctic Research Expedition (1947–1948). The Falkland Islands Dependencies Survey took from 1948 to 1950 surveys before. The UK Antarctic Place-Names Committee named the cliffs in 1974 after the American astronomer Clyde Tombaugh (1906-1997), who discovered the (dwarf) planet Pluto in 1930 , who gave the neighboring glacier its name.
