Byrd Glacier - Satellite Photography quotation long-extinct volcano on the borderTruly a river of ice, Antarctica's relatively fast moving Byrd Glacier courses through the Transantarctic 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.
