Antarctica's Dry Valleys, with their barren gravel-strewn floors, are said to be the most similar place on Earth to Mars. Its fascinating landscape, 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’s 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.
