From its distinctively shaped recess on the border between Ontario and New York, the Horseshoe Falls tumble down to meet the Niagara River with a fierce intensity. Together with the Bridal Veil Falls and the American Falls, the Horseshoe Falls form the collective attraction of Niagara Falls, set on the mighty river. Also known as the Canadian Falls, this colossal cascade began its descent 11 kilometers (6.83 miles) downstream from where it is today several millennia ago, arriving at its current spot as a result of rigorous erosion. Today, studies show that erosion has greatly reduced, and Horseshoe Falls are deemed to be one of the primary sources of hydraulic power in the region.
