The sight, sound and power of rushing water cascading off a cliff has a mesmerizing effect on us. The beauty the tens of thousands of waterfalls nature provides us with is truly something to behold. If you are planning a model railroad layout be sure to include one on it. Make sure you provide a mountain with the appropriate stream and pond below for your waterfall to empty into. They are not as difficult to build and crystal clear caulk which you will streak with white paint does the trick!
