The Hidden History Beneath 1720 South Scenic Highway

The drill was driving down through Lookout Mountain when the work changed course.

In 1928, Leo Lambert and his team were cutting an elevator shaft intended to reopen Lookout Mountain Cave to tourists. During the excavation, they broke into a passage no one on the crew had expected to find: a previously unknown cavern system inside the mountain.

That accidental opening became the first chapter in the history attached to 1720 South Scenic Hwy, Chattanooga, TN—the address now associated with Ruby Falls.

Lambert entered the newly revealed passage and explored deep into the mountain. The route was difficult, but it eventually brought him to a remarkable sight: a 145-foot waterfall descending into a pool underground.

He named it Ruby Falls for his wife, Ruby Lambert. She accompanied him on a later exploration of the cavern, seeing the place that would carry her name far beyond their lifetimes.

The name makes the attraction sound almost inevitable. It was not. Ruby Falls began with industrial work, physical risk and a surprise inside old rock. An elevator shaft meant to reach one cave exposed another, and Lambert recognized that the discovery could become a place people would travel to experience.

He developed Ruby Falls as a tourist attraction. Today, visitors still descend by elevator into Lookout Mountain, continue on foot through the decorated cavern and arrive at the dramatically illuminated waterfall.

That sequence matters to the memory of the address. At most historic properties, the building is the main event: a façade, a staircase, a porch or a room where something consequential happened. Here, the defining space is below the property. The address is merely the fixed point on a map for a story buried inside the mountain.

I live in Los Angeles, where addresses often carry several erased versions of themselves. But 1720 South Scenic Highway presents a stranger kind of continuity. Its most important feature was not demolished, remodeled or replaced. It was hidden until someone happened to open a way in.

The site also captures a particular moment in American tourism. Lambert was not satisfied simply to document the cavern and waterfall. He found a way to make the underground landscape accessible to visitors. The elevator remains central to that experience, linking the practical purpose of the original 1928 project with the attraction that emerged from it.

Ruby Falls is now presented with theatrical lighting, but the essential wonder does not depend on the staging. Water falls 145 feet inside a mountain. The drama was already there; the illumination allows visitors to see it.

Properties with public histories depend on careful stewardship. Site operators, historians and licensed real estate professionals all play a role in keeping an address tied to accurate records rather than loose folklore. In this case, the documented core is compelling enough: Lambert’s crew drilled an elevator shaft, uncovered an unknown cavern, and Lambert followed it to a waterfall he named after Ruby.

The result is a Chattanooga landmark born from an accident but sustained by intention. Discovery made Ruby Falls possible. Lambert’s entrepreneurial work turned it into a destination. Continued care has allowed generations of visitors to make the same descent and stand before the same underground cascade.

That is what makes the 1720 South Scenic Hwy, Chattanooga, TN history worth preserving. It reminds us that an address can contain more than the structures visible from the road. Sometimes its deepest story is literally beneath it.
