This article just showed up today about the blonde haired, white skinned nation of people called the Cloud People or Chachapoyas. The site is reported to be about 4.2 hectares in size. What drew the people that found the site to it was the sound of an enormous waterfall they found to be 500 metres tall situated at the site. http://www.nowpublic.com/world/lost-city-cloud-people-discovered-perus-amazon The site was free of looting because of its remote and untouched location. Burials, household items and ceramics are all in situ and undisturbed. I chose this site to report the find because it has a photo of a Chachapoyas settlement that was found near by the site. This gives you an idea of their engineering skills and techniques.
