Cave divers in Mexico's Yucatan peninsula have discovered what may be the world's longest underground river, connecting two cave systems with a waterway at least 95 miles long.
A group of foreign divers exploring the area near the Caribbean beach resort of Playa del Carmen have yet to name the stretch, but believe it could be connected to two other major systems, adding more than 125 miles to its length.
"A stunning survey of the latest evidence for intelligent life on Mars. Mac Tonnies brings a thoughtful, balanced and highly accessible approach to one of the most fascinating enigmas of our time."
--Herbie Brennan, author of Martian Genesis and The Atlantis Enigma
"Tonnies drops all predetermined opinions about Mars, and asks us to do the same."
--Greg Bishop, author of Project Beta
"I highly recommend the book for anyone interested in the search for extra-terrestrial artifacts, and the political intrigues that invariably accompany it."
--David Jinks, author of The Monkey and the Tetrahredron
"Mac Tonnies goes where NASA fears to tread and he goes first class."
--Peter Gersten, former Director of Citizens Against UFO Secrecy
