"In the first major Inca find in four decades, Peruvian and British explorers say they have discovered a hidden city...Located on a narrow ridge around 11,000 feet up in Peru's windswept, southern Andes, the Inca citadel of Corihuayrachina is a mysterious gathering of religious platforms, funeral towers, and food storehouses...It is about 22 miles southwest of the famous Inca citadel of Machu Picchu....

Peter Frost said he found Corihuayrachina -- eyeing it from afar but not able to actually reach it -- when he was leading a group of tourists through the remote region in 1999. Funded by National Geographic Society, Frost was finally able to set foot on the cloud-shrouded site two years later in June, 2001, trekking four days along winding mountain paths with a team of scientists and excavators". A television special will screen in May.
