General Information

St. Louis




  • All caves on this and other Conservation Areas are currently closed or restricted to public access. The fungus that causes White-nose Syndrome in bats was found in Missouri in 2010, resulting in the Missouri Department of Conservation’s White-nose Syndrome Action Plan that limits public access to protect bats. WNS can be spread from cave to cave by bats or possibly on the gear of explorers. Privately owned caves are not affected by this Plan.
