Near Lewiston, New York, the Niagara River comes off of Niagara Falls to Lake Ontario. It is a wide and very fast river that looks dangerous to swim and boat on to me. There were huge currents and swirls even miles down from Niagara Falls. This image was stitched together from three photographs. Note how the shoreline is muddy and the water out in the middle is blue-green. The green forests across the river is Canada.
