This World Heritage site in Argentina is a must see! The Cueva de las Manos (the Cave of Hands) in Patagonia in the province of Santa Cruz, Argentina, contains an exceptional assemblage of cave art. The cave gets its name from the cluster of stenciled outlines of human hands that appear on the cave walls. These rock paintings were made by hunter-gatherer communities estimated to have lived between 13,000 and 9,500 years ago, as determined from the remains of bone-made pipes used for spraying the paint on the wall of the cave to create silhouettes of hands.
