Description
(see definition):
Cliffs, 610 m, marking the E face of the sedimentary ridge between Mercury and Venus Glaciers, on the E coast of Alexander Island. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on Nov. 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The cliffs were roughly surveyed in 1936 by the British Graham Land Expedition (BGLE) and resurveyed in 1948 by the Falklands Islands Dependencies Survey (FIDS). So named by the Falklands Islands Dependencies Survey (FIDS) because the geologic structures revealed in these cliffs provided the key to the general tectonic structure of the area.
