During recent years substantial information has been garnered about the glacial and subglacial topography of Antarctica. In this paper the numbers and types of observations which produced this information are presented in tabular form. Major geographic discoveries in the Filchner and Amery Ice Shelf regions, in eastern Victoria Land, and in West Antarctica are briefly discussed. The glacial surface of East Antarctica consists of a fairly simple dome-like structure; in West Antarctica a saddle shaped surface shows ice drainage chiefly into the Ross and Amundsen Seas. A map of subglacial rock surface elevations shows the glacial bed in East Antarctica to be largely near sea level where known. In West Antarctica the bed beneath about half of the region investigated is below ‘adjusted’ sea level, but the predicted connection between the Hoss and Bellingshausen Seas has been found not to exist.
