cr4ck: Ruby Falls | Chattanooga, Tennessee This is Ruby Falls, a 150-foot tall underground waterfall that is 1,100 feet below the surface of Lookout Mountain in Chattanooga, Tennessee. One reaches the falls by descending 26 floors into the mountain via an elevator shaft leading onto a 1/2 mile hike into the heart of the mountain itself. The euphoric colors come from the lighting installed by the park service (which actually cycle through a series of colors and natural lighting as you enter the cavern the falls is located in).
