The Drakensberg Mountains are Southern Africa's Alps, rising more than 11,000 feet into the sky. But beneath their shimmering beauty lies an incredibly hostile environment for the creatures that manage to live there. Each spring, drenching rains destroy the grasslands at the base of the mountains, and those who would survive must climb up sheer cliffs of volcanic rock, through gauntlets of storms and snow, to reach the carpets of new grass on the plateau. The baboons that make their home halfway up the heights may have the advantage of agility, but eland, the world's largest antelope, have long, spindly legs and heavy bodies, which make their climb to the top all but unbelievable. All have babies at their sides. And the vultures circle overhead.
