Wohlthat Mountains
The Astor Rocks () are two small rock outcrops lying southeast of Mount Ramenskiy in the southeast extremity of the Wohlthat Mountains. They were plotted from air photos and from surveys by the Sixth Norwegian Antarctic Expedition (NorAE), 1956–60, and named for Astor Ernstsen, a meteorologist with the NorAE, 1958–59.
