Niagara Falls is retreating

Nature teaches us to believe in the power possessed by little things. Not only can water falling with tremendous power over falls create the waterfall basin, but the down side is that above the waterfall, just before the water begins its decent, by retractive movement it causes the falls to retreat through constant erosion of the bedrock. Over a period of 12,000 years, Niagara Falls has retreated 11 kilometers, with yearly erosion averaging 3-5 meters. The same action can also be observed at Kegon Falls when you walk down toward the basin. In Kagoshima Prefecture, surpassing even Sakurajima there is the No. 1 attraction of a waterfall that still remains in the 21st century—Inukai Falls, which can be seen when traveling along Amori River headed for Kirishima Onsen (Hot Springs) if you look toward Takachiho Peak. This is the route taken by Ryoma Sakamoto when he traveled with his bride, Oryo. It has only been 150 years since Sakamoto viewed this waterfall, but no doubt the sight has changed since then because of regressive activity.
