Ruby Falls is believed to be 30 million years old.
Lambert, along with a small crew, entered this opening to explore the new found cave.
While exploring they discovered a number of unusual and beautiful rock formations, flowing passages and several stream beds.
Pushing their way deeper and deeper into the cave, they finally reached its marvelous jewel, the waterfall.
It was then Lambert decided to call the waterfall Ruby Falls.
Ruby Falls proved to be the most popular with its many unusual formations and of course the waterfall itself.
Lack of public enthusiasm finally lead to the closure of the Lookout Mountain Cave in 1935.
Development of the Ruby Falls Cave continued.
Later elevators were added to provide hundreds of thousands of visitors easy access to the caves each year.
