What a name "American Falls". Like water doesn't go to the same river that wash the banches of both America and Canada. But yes, I understand the comfort of using this name. Briefly, it is the Fall that on the American side.
Fondest memory: What I liked to see the most is small figures of people on another side of Niagara River that like small ants moved on the hills of the fall being guided to the roaring falling water. It is easy to spot them, because they wear those yellowish panchos.
At the American Falls the water's vertical descent ranges from 21 to 34 metres (70 to 110 feet) to the rock at the base of the Falls.
At 56 metres (180 ft) high, the American Falls is slightly higher than its Canadian counterpart. Its crestline is 328 metres (1075 ft) wide.
The natural bedrock is composed of soft shale and limestone. Over the years the continual flow of water causes large sections of bedrock to fall and remain at the base of the cataracts.
Geologists predict that eventually the American Falls will transform into a succession of descending rapids.
The diversion of water above the falls has slowed the forces of erosion. It is estimated that 75,000 gallons of water flow over the American Falls each second, amounting to only 10% of Niagara's total waterflow.
No one has ever dared to conquer the American Falls in a barrel. All daredevil activities have always concentrated on the Canadian Horseshoe Falls because it has a larger waterflow and fewer rocks at its basin.
Fondest memory: My best impression from this Fall were rocks at its basis and flying birds so low and so close to water splashes, that I always worried one of them will fall down on the rocks. Scary thoughts, huh?
