The more North America is explored, the clearer it is that a number of advanced ancient civilizations existed there, rivaling the civilizations of Mexico and Central and South America. Some of the most fascinating archeological finds are the sophisticated stone walls of Southern Indiana, built as fortresses for protection, as living quarters, enclosures for livestock, water management and erosion control.

Built from local materials, these walls may have supported a large population with mining, sawmills, textile mills, or other processes. Even more astounding is the prospect these walls represent a truly ancient transportation system, a cable tram to deliver supplies and water, something not regarded as North American, but closer to engineering found in Europe and the Middle East!
