Jun 10, 2023 · Limestone typically forms in warm, shallow seas, and is commonly located in regions with high concentrations of marine life, such as coral reefs. As time passes, the sediments and marine organisms accumulate, compact, and cement together, resulting in the formation of limestone rocks. There are three limestone formations that make up the cave system: the Girkin, St. Genevieve, and St. Louis. The Big Clifty Sandstone formation acts as protective layer at the top of ridges. Mammoth Cave’s passages descend through a total thickness of 300 feet of limestone, occupying all of the Girkin and St. Genevieve, and half of the St. Louis.
