Believed to be roughly 12 thousand years old, Niagara Falls consists of three distinct waterfalls. Horseshoe Falls, at 2500 feet, has the longest span. In 1901 Annie Edson Taylor, the first so-called Niagara Daredevil, rode over the falls in a wooden barrel. Twenty more brave souls would follow her over the next century. Including Taylor, only 16 would survive.
