The Niagara Escarpment is an approximately 1,050-kilometre-long (650-mile) discontinuous, arc-shaped, but generally northward-facing escarpment, or cuesta, in Canada and the United States. The escarpment begins south of Lake Ontario and circumscribes the top of the Great Lakes Basin running from New York through Ontario, Michigan, and Wisconsin.
