For this wonderful day we - means Rob, Vroni, Sabine and me, have planned to visit the Niagara Falls. We are still not over the Hawaiian party the night before, so we don't get started very well. A breakfast altogether is waking us up and so we get on our way sometime after noon.
To whom it may concern: The Niagara Falls belong to the biggest, most interesting and famous falls of the world. Over a 50-60 meter high terrace the water is falling down and squeezes itself through a 80-300 meter broad canyon until Lake Ontario. 90 % of the water flows over the Horseshoe Falls, which are made up by a 675 meter long edge.
The development of the falls reaches back to the last ice age. In this time the river was flowing on a higher level of a limestone plateau, which is part of the Niagara Escarpment. In former times the terrace had been located much closer to the Ontario Lake, but due to erosion was moving upstream very fast. In present time erosion has slowed down significantly, because a great part (approx. 50 %) of the water is diverted through hydroelectric power plants. Therefore the edge is moving only about 6-30 cm per year. Despite the diversion about 6000 m3/s are passing the edge.
However, here are the pictures:
Niagara Falls City, which has moved its outer concrete front close the falls, isn't that remarkable and so we stay for only one and a half hours before we head back to Waterloo.
