Explore the hidden industrial history beneath one of the world's most famous waterfalls in this 20-minute documentary video. Discover how engineers carved massive underground tunnels into solid rock beneath Niagara Falls over a century ago to harness the power for factories, mills, and pioneering hydroelectric plants that helped establish North America as a major industrial hub. Learn about the underground hydraulic canals, tailrace tunnels, and infrastructure systems that played a crucial role in the War of Currents and demonstrated electricity's potential for long-distance transmission. Examine the engineering marvels from early industrial wheel pits to the catastrophic collapse of the Schoellkopf Power Station, while uncovering why most of these remarkable tunnels are now sealed, flooded, or forgotten, and which few systems still survive beneath this natural landmark today.
