Cold Water Falls is described as the world's largest man-made natural stone waterfall known to exist, measuring 80 feet wide and 48 feet tall. Built with 1,780 tons of Colbert County sandstone, it carries 4,320,000 gallons of water per day over the falls. The largest stone weights are 77,000 pounds, and construction took 120 days.
