After driving by road signs for the last 40 years, I finally broke down and went to “See Rock City” and Ruby Falls. I have to say it was worth it. Ruby falls is much more commercialized than Mammoth Cave and has been somewhat abused over the years. However, it is absolutely worth seeing.
Ruby Falls is a 145-foot high underground waterfall located within Lookout Mountain, near Rock City and Chattanooga, Tennessee in the United States. The cave which houses Ruby Falls was formed with the formation of Lookout Mountain. The Lookout Mountain Caverns, which includes Ruby Falls Cave, is a limestone cave. These caves occur when slightly acidic groundwater enters subterranean streams and eats away at the relatively soft limestone, causing narrow cracks to widen into passages and caves in a process called chemical weathering. The stream which makes up the Falls entered the cave sometime after its formation.
