Do you crave more information, beyond the basics? Check out the articles on the BPI blog or read Backyard Bigfoot by Lisa A. Shiel for deeper discussions of ancient mysteries.

"Human cultures have a tendency to spring up out of nowhere, then vanish or regress with equal abruptness. The Anasazi, the ancient Maltese, the residents of Teotihuacán in Mexico and Tiahuanaco in Bolivia — all these cultures sprang up, flourished, and vanished without a trace. They also built enormous, megalithic structures whose purpose and construction techniques remain a mystery."
