Johnson Shut-Ins State Park and the surrounding Ozark landscape are defined by the dramatic engineering and geology of the St. Francois Mountains at the end of the twentieth century. The map centers on the East Fork Black River, which flows through the iconic Johnson Shut-Ins before reaching the massive Lower Reservoir. This area is a site of significant energy production, featuring the Taum Sauk Pumped-Storage Hydroelectric Powerplant and the Upper Reservoir perched atop Proffit Mountain.
