Discovering Ruby Falls

Geological Significance of Lookout Mountain
Lookout Mountain is part of the Appalachian Plateau, a geologic region characterized by sedimentary rock layers that date back hundreds of millions of years. The cave system housing Ruby Falls is formed from limestone, a rock type highly susceptible to erosion from slightly acidic water. Over time, underground streams carved out tunnels and chambers, creating the unique environment we see today.
Ruby Falls is a rare example of a subterranean waterfall formed inside a limestone cave, making it an important site for both geological study and public education.
Key Geological Facts:
- The cave was formed during the Mississippian period, approximately 350 million years ago.
- Water flowing from the Cumberland Plateau feeds the waterfall.
- Ongoing mineral deposits continue to shape new cave formations.
