American Falls
Quick Summary
The American Falls is one of the three waterfalls that make up Niagara Falls, located on the border between Ontario, Canada, and New York state, U.S.. It is 190 feet (58 meters) high and 1,060 feet (320 meters) across. The falls are separated from the larger Horseshoe Falls by Goat Island. The unique geological formation of hard dolomite overlying softer shale allows the falls to maintain a vertical cascade as the shale erodes more quickly. While historically a site for daring stunts, its primary appeal now lies in its natural beauty. Public parks on both the U.S. and Canadian sides offer excellent viewing points.12
