Donaldson/Bronson Cave (also known as Shawnee Cave) is located entirely within Spring Mill State Park. The cave is the downstream section of the Shawnee drainage system (Lower Twin and Upper Twin caves make up the remaining sections). For the entire length of the cave, you are in water.
The cave is named for Agave lechuguilla, a species of plant found near its entrance. Lechuguilla is in Carlsbad Caverns National Park, New Mexico. Access to the cave is limited to approved scientific researchers, survey and exploration teams, and National Park Service management-related trips.mall amounts of bat guano were mined from the entrance passages for a year under a mining claim filed in 1914. The historic cave contained a 90-foot (27 m) entrance pit known as Misery Hole, which led to 400 feet (122 m) of dry dead-end passages.
