The Baltoro and other glaciers of the Karakoram, Pakistan are the largest and longest in the world outside the polar region. From it's spectacular birthplace in Concordia, at the base of K-2 and the gasherbrum range, the Baltoro Glacier flows for more than 59 kilometers, a rippling, pitted, pockmarked river of ice, where great glaciers slide and slither together before separating to go their different ways.
