A hiker climbs a rocky slope at the base of the jagged Cerro Torre Massif in the Patagonia region of southern Argentina. The sheer granite peak, so treacherous it was thought to be "unclimbable" until a team summitted it in 2005, rises more than 4,000 feet (1,219 meters) from the glacier at its base.

A woman guides her horse through a wind-blown valley in Chilean Patagonia as the jagged, snow-clad towers of the Torres del Paine rise in the background. The rugged Paine range was formed when plateaus of granite were thrust upward by tectonic collisions, then carved away by ancient retreating glaciers.

A skier glides past a fractured section of ice and snow in the Cordillera Sarmiento of Patagonia, Chile. This area is the highest point in the South American ice cap, a series of interconnected Andean glaciers that cover more than 5,000 square miles (13,000 square kilometers).

A cautious caver descends a heavily eroded limestone wall on Madre de Dios Island in Chilean Patagonia. The island, located off the cold, wet coast of southern Chile, is made up of coral limestone laid down near the Equator some 300 million years ago and later thrust to the surface by tectonic forces.
