Dry Valleys of Antarctica

Journey Through the Otherworldly Landscape

The Dry Valleys of Antarctica (located within Victoria Land west of McMurdo Sound) get almost no snowfall, and except for a few steep rocks they are the only continental part of Antarctica devoid of ice. The terrain looks like something not of this Earth; the valley floor occasionally contains a perennially frozen lake with ice several meters thick. Under the ice, in the extremely salty water live mysterious simple organisms, a subject of on-going research.

Recent Washington Post interactive presentation
(featuring photography by George Steinmetz) reveals this stark but beautiful terrain like never before – in some places weirdly similar to Martian landscape:

Looking like something out of Lovecraft’s (“Mountains of Madness”) imagination, this is actually a dried skeleton of a seal.

Taylor Valley: Powerful “katabatic” winds erode the rocks on the bottom of the valley into marvelous shapes. Such wind-sculpted rocks are called “ventifacts”:

Mount Erebus (3,794 meters), Ross Island, is the most active volcano in Antarctica, which also contains “persistent” lava lake, one of a very few long-lived lava lakes in the world – clearly visible from space:
