They were travelling on foot and their first sight of this mountains must have been daunting1 indeed. In front of them stretched one of the world's longest ranges, spanning two thousand miles from one side of the continent to the other. The winds uphill are the fastest on earth. They reach speeds of two hundreds an hour. An ice capped mountain bears its cuts of the gales2, bizarre sculptures carved from solid ice. It's not only the ice that yields. This sculpture spire3 is surrender of a mountain that raided from all sides by the ferocious4 elements.
Beyond, a holy unexpected landscape, the dry valleys. Only one percent of Antarctica is free of ice, and most of that bear rock. It's here. The dry valleys are more like the surface of Mars than is any other place on earth. The floor is covered with extraordinary natural sculptures, created by the same winds that help to keep these valleys free of snow. Over time, entire
boulders5 are weathered from the inside out until just a shell
remains6. At the head of these valleys, ice is making a breakthrough. Millions of tons are tumbling in slow motion into the valley.
