Ruby Falls

In the 1920s, Leo Lambert thought Lookout Mountain Cave would make a great tourist attraction. Once used as a hideaway for outlaws, refuge for Native Americans and a hospital during the Civil War, a railroad tunnel built in the early 1900s intersected the cave’s entrance and sealed it from the public. But that didn’t deter Lambert from searching for the cave. In 1928, he led a team of engineers and started digging an elevator shaft to access the cave. Ninety-two days later, Lambert found the cave, but not before digging through more than 400 feet of solid limestone. But when Lambert realized there might be more than just a cave buried beneath Lookout Mountain, he took off down a tight corridor, and 17 hours later, he found what today known is as Ruby Falls.
