Antarctica without its ice cover. This map does not consider that sea level would rise because of the melted ice, nor that the landmass would rise by several hundred meters over a few tens of thousands of years after the weight of the ice was no longer depressing the landmass.
In Antarctica there are, in addition to mountaintops and nunataks, other natural snow- and ice-free areas often referred to as "Antarctic oases" or "dry valleys". [1] [2] These areas are surrounded by the Antarctic ice sheet or, in coastal areas, are situated between the ice sheet and the Antarctic ice shelves.
The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross Sea. At 4,800 square kilometres (1,900 sq mi), the valleys constitute ...
<p>Chances are you make it through most days without sparing a thought for Antarctica. At just over 5.4 million square miles, it's a massive chunk of land that is nearly twice the size of ...
Topographic map of Livingston Island, Greenwich, Robert, Snow and Smith Islands. Viskyar Ridge (’rid vis-’kyar) is a rocky ridge rising to 600 m and extending 2.5 km in north-south direction in Breznik Heights, Greenwich Island in the South Shetland Islands, Antarctica. The ice-free surface area of the ridge is 135 hectares (330 acres). [1]

Location of Snow Island in the South Shetland Islands. Topographic map of Livingston Island, Greenwich, Robert, Snow and Smith Islands. Hall Peninsula is a small ice-free peninsula on the southeast coast of Snow Island in the South Shetland Islands, Antarctica.
Byers Peninsula is a mainly ice-free peninsula forming the west end of Livingston Island in the South Shetland Islands of Antarctica. It occupies 60 km 2 (23 sq mi), [ 1 ] borders Ivanov Beach to the northeast and is separated from Rotch Dome on the east by the ridge of Urvich Wall .
