Johnson's Shut-Ins State Park, Reynolds County, Missouri


Johnson's Shut-Ins State Park is a public recreation area covering 8,781 acres (3,554 ha) on the East Fork Black River in Reynolds County, Missouri. The state park is jointly administered with adjoining Taum Sauk Mountain State Park, and together the two parks cover more than sixteen thousand acres in the St. Francois Mountains region of the Missouri Ozarks.

The term "shut-in" refers to a place where the river's breadth is limited by hard rock that is resistant to erosion. In these shut-ins, the river cascades over and around smooth-worn igneous rock, creating a natural water park that is used by park visitors when water levels are not dangerously high.

The bedrock of the area is an erosion resistant rhyolite porphyry and dark colored diabase dikes of Proterozoic age. Waters of the East Fork Black River became confined, or "shut-in," to a narrow channel following fractures and joints within the hard igneous rock. Water-borne sand and gravel cut deeply even into this erosion-resistant rock, carving potholes, chutes and canyon-like gorges.
