The Ruby Falls Cave is found deep in the heart of Lookout Mountain, just minutes from Chattanooga in Tennessee. It is a limestone cave that is known for its many unusual geological features. As Olivia mentioned, here you’ll find Ruby Falls, a 145-foot underground waterfall located more than 1,120 feet beneath the mountain’s surface. The water from Ruby Falls flows through the cave and then into the Tennessee River. Did you know that people who explore caves are called spelunkers?

Some of the formations are given names because of how they look.

This photo shows more unusual cave formations.

These formations are known as ‘Frozen Niagara’.

This is Ruby Falls waterfall without the purple lighting.

This curtain formation, highlighted in red and blue, is called ‘Ruby’s Drapery’.
