How was niagara falls formed. The brown colour is clay which contains suspended particles of. Constant refreezing and thawing of the Niagara River continues to have an effect on the falls moving them slowly upstream due to erosion. The Story of the Falls began 600 million years ago.

The falls were formed the riverbed dropped off suddenly like an underwater cliff. Niagara Falls was formed by melting ice that drained down the Niagara River at the end of the Ice Age and dropped off a cliff called the Niagara Escarpment. The height of the initial Niagara Falls was only 11 meters 35 feet as it flowed over the Niagara Escarpment at Queenston to the waters of Lake Iroquois below.
As the water flowed over the escarpment to the water below the water began eating through the glacial material and the limestone rock of the Niagara Escarpment to begin the formation. The Escarpment has hard limestone on top and soft shale below. Water raced over this cliff forming Niagara Falls.
