Niagara Falls (CR-L-NF01)
Niagara Falls are large waterfalls located on the Niagara River, on the border between Canada and the USA. There are two main waterfalls, the American Falls on the USA side, and the larger Horseshoe falls on the Canadian side.
Due to the power of the water, the falls are constantly eroding. To slow this process, the local authorities acually reduce the flow of water over the falls at night time.
