Close to the Southern border of the Amazonian Province of Pastaza, Ecuador; marked by a line running due east from Mount Sangay converging with another running due south from Mount Sumaco: concealed below river level inside a treacherous section of the Tayos Caves System, some kilometers in length, formed by the River Pastaza.

Pastaza River Stretch of Tayu Cave Location


After separate odysseys with Moricz and another key protagonist Hall broke his rule of rejecting any treasure, monster or ufo that cannot be dragged up to his front door, or that Steven Spielberg can replicate, by finally accepting the Tayos metal library and treasures had to exist! Packed with scientific and historical information but lacking an ancient script in South America he distilled from Mytho-history a model of The Origins of the Solar System and Humanity that might accommodate the metal library...

... and a more astounding 'crystal' library that accompanies it!

Following the deaths of the two key protagonists in the 1990s Hall became sole custodian of the treasure story. Realizing such a fantastic tale could never stand on its own he developed an Optical Relativity Model (see Grailscope) to effect an empirical distillation of data gathered since 1974, finally emerging with two non-fiction and two fiction manuscripts covering his analyses and discoveries.

Stan Hall at calculated "Yacu Waa" site

Above is a photograph of the site which Hall believed best matched the descriptions given by Petronio, together with the information gathered from all other sources involved in the story. Over the years after the death of the two key protagonists, Hall ventured into the Amazon on various Reconnaissance Trips in order to further distil his information and research to help narrow down his proposed location of the treasure, on more than one occasion these trips nearly cost him his life..

A full Analysis of the Treasure and its location, along with more detailed descriptions of Hall's quest can be found in Tayos Gold: The Archives of Atlantis, for more information on this and other books in the Tayos Series visit the Tayos Books section or to buy a copy go straight to our Goldlibrary Store
