On the way out from the Great Falls, my friend said that there was a flower clock in front of it, which was composed of flowers and plants. The pattern of the clock surface would change with the flowering time, and it was called the second largest flower clock in the world. We parked and watched, surprisingly without tourists. It is said that the steel pointer of the flower clock is powered by the power of the Niagara River hydropower plant, which is energy-saving and environmentally friendly.
