Marvin & Huck: Mammoth Caves for Days

Mammoth Cave National Park has been designated both a World Heritage Site and an International Biosphere Reserve by UNESCO. Did you know that the temperature inside Mammoth Cave is about 54°F, year-round? The cave has more than 390 miles of cave passage mapped, making Mammoth Cave by far the longest known cave in the world. But guess what? They are still mapping!  The four rock formations found in Mammoth Cave are the St. Louis Limestone, the Ste. Genevieve Formation, the Girkin Formation, and the Big Clifty Formation.
