Shawnee Cave (also called Donaldson Cave or Donaldson-Bronson Cave) is located in Spring Mill State Park in the state of Indiana. Access to the cave is controlled by the Indiana Department of Natural Resources.
Shawnee Cave, consists of just over 8,000 feet of passage, which is actually the lower stream-portion of Twin caves, also located in Spring Mill State Park. Shawnee cave can be entered through the Bronson Cave Entrance and exited via the Donaldson Entrance. The lower portion connecting Shawnee cave to Twin caves is extremely dangerous and is off limits.
Unfortunately, all caves controlled by the Indiana DNR are off limits as the state attempts to battle White nose syndrome, which is contracted by bats. It is believed that humans track the fungus into the caves when we walk in. Once this ban is lifted, access to Shawnee Cave can be arranged by visiting the Park office at Spring Mill State Park. However, it is unknown when the ban will be lifted, as it was in effect for the 2009 season and has been renewed on a yearly basis.
