Byrd Glacier, Antarctica
Sometimes I like being reminded that life in all its forms is utterly awesome. The image and text are from Wired Science
Truly a river of ice, Antarctica's relatively fast-moving Byrd Glacier courses through the Trans-Antarctic Mountains at a rate of 0.8 kilometers [0.5 miles] per year. More than 180 kilometers [112 miles] long, the glacier flows down from the polar plateau (left) to the Ross Ice Shelf (right). Long, sweeping flow lines are crossed in places by much shorter lines, which are deep cracks in the ice called crevasses. The conspicuous red patches indicate areas of exposed rock.
