Geology

When you think about geology, you may picture mountain chains, rugged coastlines and rock layered plateaus, canyons, and cliffsides. While geology often shows us wonders on earth’s surface, it would be incomplete without thinking about the world beneath us, where rock beds have formed for over hundreds of millions of years. Caves like Mammoth Cave let us explore this ancient world by allowing us to walk through the rock layers and see the earth’s formation up close.
