A Shelter Throughout Time

Forming of Cliff Cave
Rainwater and melting snow are stronger than they seem! Caverns like Cliff Cave form when water soaks into cracks and pores of limestone rock, mixing with carbon dioxide to form carbonic acid. The acidic water finds its path through crevices, expanding and creating wider passageways as it goes. It can take 100,000 years to create a cave large enough for a human to fit in.
Since prehistoric times, people have sought shelter in caves. Drawings, pottery vessels, organic material, stone tools, and weapons from early civilizations have been found in caves in Missouri and around the world.
A Place to Chill and a Place to Hang
Cliff Cave stays at a consistent fifty-seven degrees Fahrenheit year-round. If you've ever been in a cave during the summer months, you may have felt like you were walking into an air conditioned room or a refrigerator. In the mid-1800s, Cliff Cave was used by the Cliff Cave Wine Company as a wine cellar. The wine company built the rock walls at the entrance of the cave that you see today.
Of the fifteen bat species found in Missouri, five are known to reside inside Cliff Cave. These include the federally endangered Gray Bat and Indiana Bat. These bats hang upside down in hibernation in the cave during the winter. During the rest of the year, they nest in trees in the park and wooded areas along the Mississippi River. Bats feed on insects and help keep insect populations balanced. Cliff Cave has limited public access to protect the endangered bats in the cave and to prevent potential danger to humans caused by flash flooding in the cave.
Indian Cave
This cave has been called "Indian Cave" because Native Americans once used the cave for shelter and storage of food and goods. Chert rock tool fragments embedded in the clay floor at the entrance are evidence of Native Americans occupying the area prior to the 1600s. Osage people who lived in this area used the cave for centuries, using the front of the cave as shelter and deeper areas for ceremonies. Thanks to the high entrance ceilings and spacious, dry floor, the cave would offer welcome refuge against harsh winter winds with fresh drinking water from the spring nearby. The cave is close enough to the river for fishing, working, and traveling, but
not too close as to be flooded during the rainy season.
During cold, winter days the cave produces a unique mist that makes the cave look like it is "breathing." Cliff Cave is still considered a Sacred Site by the Osage Nation today.
