The Power of NatureExplore the ancient geological forces that created Niagara Falls and the relentless process of erosion that continues to shape this natural wonder. This section delves into the deep history written in the rock and the dynamic systems that define the Falls today. A Landscape Carved by IceThe story of Niagara begins hundreds of millions of years ago at the bottom of a tropical sea. Layers of sediment and ancient coral reefs were compressed into the rock formations we see today. The hard, erosion-resistant Lockport Dolostone forms the caprock, while softer shales lie beneath. This geological sandwich is the key to the Falls' existence. The last Ice Age delivered the final, dramatic touch. As the massive Wisconsin Glacier retreated about 12,000 years ago, it unleashed immense torrents of meltwater, carving out the Great Lakes and the Niagara River. When this new river flowed over the Niagara Escarpment, the Falls were born. The Engine of ErosionQueenston Shale (Soft)

Water Flow Undercutting The Falls' sheer face is maintained by a process called differential erosion. The powerful river scours the soft shale layers beneath the hard caprock, creating an undercut. Eventually, the unsupported caprock collapses, maintaining the vertical drop and causing the Falls to retreat upstream. A Relentless Retreat: An 11km JourneyBorn near modern-day Lewiston, the Falls have carved the 11km (7 mile) Niagara Gorge by retreating upstream over 12,000 years.

This section explores our complex relationship with this powerful place. From Conflict to ConservationThe first people arrived 13,000 years ago, viewing the Falls as a place of spiritual power. European arrival in the 1600s turned the region into a strategic frontier, culminating in the War of 1812. By the 19th century, unchecked tourism threatened to ruin its beauty. This degradation sparked a pioneering conservation movement. Led by figures like Frederick Law Olmsted, this resulted in the creation of public parks on both sides of the border in 1885 (USA) and 1888 (Canada), a landmark act of international cooperation to preserve a shared natural treasure. Dancing on the Brink: A History of DaredevilsThe Falls' fame has long attracted individuals seeking to conquer it for fame and fortune. Filter the list below to explore their stories. Taming the GiantThe same force that inspires awe also represents an immense source of energy. This section chronicles the ambitious saga of harnessing Niagara's power, a story of innovation, conflict, and engineering that lit up the world. The War of CurrentsThe late 19th century saw a battle between Thomas Edison's direct current (DC) and Nikola Tesla's alternating current (AC). Niagara became the ultimate proving ground. In 1896, the Edward Dean Adams Power Station, using Tesla's AC technology, sent electricity 25 miles to Buffalo, NY. This event was a resounding victory for AC, establishing the system that powers our world today and marking the birth of the modern electrical grid. A Delicate BalanceThe insatiable demand for power clashed with tourism. The 1950 Niagara River Water Diversion Treaty was the solution. This international agreement dictates how much water can be diverted for power, ensuring a spectacular flow for tourists during the day while maximizing power generation at night. Up to 75% of the river's flow is redirected to power plants through massive tunnels. Niagara vs. The World's TitansWhile not the tallest or widest, Niagara's power lies in its immense volume.
