Dr. Richard Sauder’s second book Underwater and Underground Bases is an explosive, eye-opening sequel to his best-selling, Underground Bases and Tunnels: What is the Government Trying to Hide? Dr. Sauder lays out the amazing evidence and government paper trail for the construction of huge, manned bases offshore, in mid-ocean, and deep beneath the sea floor! Bases big enough to secretly dock submarines! Official United States Navy documents, and other hard evidence, raise many questions about what really lies 20,000 leagues beneath the sea. Many UFOs have been seen coming and going from the world’s oceans, seas and lakes, implying the existence of secret underwater bases. Hold on to your hats: Jules Verne may not have been so far from the truth, after all! Dr. Sauder also adds to his incredible database of underground bases onshore. New, breakthrough material reveals the existence of additional clandestine underground facilities as well as the surprising location of one of the CIA’s own underground bases. Plus, new information on tunneling and cutting-edge, high speed rail magnetic-levitation (MagLev) technology. There are many rumors of secret, underground tunnels with MagLev trains hurtling through them. Is there truth behind the rumors? Underwater and Underground Bases carefully examines the evidence and comes to a thought provoking conclusion!

This book is Childress' thorough examination of the early hollow earth stories of Richard Shaver, and the fascination that fringe fantasy subjects such as lost continents, UFOs, and the hollow earth have had on people. Shaver's rare 1948 book, I Remember Lemuria is reprinted in its entirety, and the book is packed with illustrations from Ray Palmer's Amazing Stories issues of the 1940s. Childress discusses famous hollow earth books and delves deep into whatever reality may be behind the stories of tunnels underground.
