The Ricker Hills (75°41′S 159°10′E / 75.683°S 159.167°E / -75.683; 159.167 (Ricker Hills)) are a group of mainly ice-free hills, about 9 nautical miles (17 km; 10 mi) long, lying just west of Hollingsworth Glacier in Antarctica. They were mapped and named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1962–63, for J.F. Ricker, a geologist with the party.[1]

Location

edit
 
Ricker Hills towards the southwest of the map

The Ricker Hills are just west of the Hollingsworth Glacier, which flows along their east side, and south of the David Glacier. The Antarctic Plateau is to their west and south, with various scattered peaks or nunataks emerging from the ice.[2]

Features

edit

Features of the Ricker Hills include the Morris Basin in the north and Benson Knob in the south.
