Tony Morrison is probably best known for his definitive work on the Nazca Lines, Pathways to the Gods. Tony and Marion Morrison have developed the South American Pictures.com website in order to show their extensive life-work.* Unfortunately, the southamericanpictures website went offline but now, many of the image collections have been reassembled and are again available online(b).
In 1998 Morrison published a number of papers provocarively entitled The Bolivian Atlantis(b-e). They cover familiar territory – Tiwanaku, Pumapunku, Posnansky, Bellamy, Fawcett, Sykes, Blashford-Snell. This was the same year that Jim Allen published his Atlantis: The Andes Solution. Had Allen not done so, I suspect that Morrison might have produced a more detailed book himself as apparently he and a colleague, Mark Howell, had built up quite a dossier on the subject.
Surprisingly, Morrison did not mention the mysterious puquios of the Nazca region(f), which, with the aid of satellite imagery(g), have been shown to have been part of a sophisticated hydraulic system that supplied water to an extremely arid locality.
