From the Stillwater New Press:
Spectacular Niagra Falls is a case study on international cooperation and agreement between two nations.
Of course, those two countries are Canada, and our good ol’ U.S. of A.
As the mighty Niagra River flows from the Great Lakes of Erie to Ontario, the incredible falls are created. The title Niagra Falls is actually a collective name for three separate waterfalls in the same general area. American Falls and Bridal Veil Falls are both located in New York state on the U.S. side, while massive Horseshoe Falls is located almost entirely in the Canadian province of Ontario. Even with two huge countries involved, both governments have interacted with each other on excellent terms over many, many years, and there is no reason to believe this mutual cooperation will not continue well into the future.
