(Nebraska)
Indian Cave State Park is a public recreation and historic preservation area covering nearly 3,400 acres (1,400 ha) along the Missouri River in southeast Nebraska. The state park preserves a cave with prehistoric petroglyphs as well as the partially reconstructed village of St. Deroin established in 1853 as part of the former Nemaha Half-Breed Reservation. The state park lies ten miles (16 km) south of Brownville and eight miles (13 km) east of Shubert, straddling the county line between Nemaha and Richardson counties.
