Vast "Cloud Warrior" Ruin Found in Amazon

Discovered in a surprising Peruvian location, a vast ruin is shedding light on an ancient civilization known for taking on the Inca Empire.

The newfound ceremonial stone structure, made public this week, was likely built by the Chachapoya Indians, a stone- and metalworking culture that thrived in Amazonian cloud forests from the 9th to the 15th century A.D.

The Chachapoya are known for building mountaintop citadels and leaving behind well-preserved mummies. Examples include cliff tombs near Peru's Lake of the Condors and Huayabamba Lake (photo of a Chachapoya mummy).

Called the Warriors of the Clouds, the battle-hardened Chachapoya were famed for their stiff resistance to Inca attacks. Nevertheless, the Inca eventually overtook the Chachapoya shortly before the arrival of Spanish explorers to Peru in the 16th century.

Found by Farmers

Originally stumbled upon by a family of farmers, the structure is exceptionally large. The stepped, three-tiered, rectangular construction is about 200 feet (70 meters) long, 100 feet (35 meters) wide, and 24 feet (7 meters) high.

The ruin's vast, impenetrable appearance prompted the farmers to call the find Huaca La Penitenciaría, or Penitentiary Ruin.

But while Penitentiary Ruin seems to have been topped by a plaza and other buildings, including a lookout tower, it was surprisingly unfortified, said Keith Muscutt, an explorer and assistant dean at the University of California, Santa Cruz. Muscutt announced the find Wednesday at an Institute for Andean Studies conference in Berkeley, California.

Perhaps more intriguing is the ruin's location.

The vast, unprotected structure was built on what has been thought to be the vulnerable eastern edge of the civlization's range—a sort of demilitarized zone between the mountain-dwelling Chachapoya and tribes of the Amazon Basin.
