Niagara Falls is on the Niagara escarpment, a massive water fall that is eating its way through the great lakes. We visit the escarpment to look at the forces that shaped and carved out the niagara canyon. The Niagara escarpment stretches across much of Southern Ontario. We visit Niagara Powerhouse, which has recently been transformed into a museum on the history of power generation and technology. Nikola Tesla had a hand in its design, built by Westinghouse and supplying 25hz it is a unique and electrical engineering masterpiece.
