Book excerpt: The reprint of Wilkin's classic book on the megaliths and mysteries of South America. This book predates Wilkin's book Secret Cities of Old South America published in 1952. Mysteries of Ancient South America was first published in 1947 and is considered a classic book of its kind. With diagrams, photographs and maps, Wilkins digs into old manuscripts and books to bring us some truly amazing stories of South America: a bizarre subterranean tunnel system; lost cities in the remote border jungles of Brazil; legends of Atlantis in South America; cataclysmic changes that shaped South America; and other strange stories from one of the world's greatest researchers.
