Underground Realms and Hidden Bases: Legends, Secret Plans, and Alien Lore from Kokoweef to Dulce
To the point
Legends describe a vast underground world of tunnels, secret bases, and connections to aliens and governments, weaving folklore about Kokoweef, Hopi lore, Mount Shasta, and Dulce with real defense plans and engineering ideas, and naming figures such as Frank P. Davidson, Charles Kaempen, Paul Bennewitz, and Gabe Valdez, while leaving it undecided whether any such network truly exists.
