Cave Walk of Tallest and Deepest Underground Waterfalls in USA || Part 1

Embark on the journey to discover more about Ruby Falls!

Ruby Falls is located at the heart of Lookout Mountain in Chattanooga, Tennessee. It is also the nation’s tallest and deepest underground waterfall. The falls are located more than 1,120 feet beneath the mountain’s surface. Ruby Falls was Tennessee’s hidden gem for millions of years until it was discovered in the early 20th century.

Over the years, the water level in the Ruby Falls cave lowered, allowing air to enter. When that happened, the conditions were right for the creation of speleothems, or cave formations. Speleothems are formed when water moving through the coil absorbs the minerals in the limestone. As the water evaporates or drips, it leaves minerals behind, creating formations over a period of time.
