This refuge exists to protect endangered species habitat.
The refuge contains abandoned iron mine shafts excavated in the mid-1800s that have since become critical habitat for the federally endangered Indiana bat. The Indiana bat hibernates within the abandoned mine shafts located at the peak of Pilot Knob Mountain. The bats generally arrive in September and leave in April.

To avoid disturbance to the bats and for public safety, the refuge is closed to all entry.
