Rock Bridge Memorial State Park is a geological preserve and public recreation area encompassing 2,273 acres (920 ha), five miles (8.0 km) south of Columbia in Boone County, Missouri off of Missouri Route 163.
The park is home to 12 caves.[5]
The state park is noted for its excellent examples of karst landforms including the rock bridge, sinkholes, and an underground stream at the cave known as Devil's Icebox. The rock bridge was created by the collapse of a section of a cave which resulted in a small arch of rock being left to form a natural bridge over the creek.[6] The park is the only known home of Kenkia glandulosa, more commonly known as the pink planarian.[7]
