1968 Map of Johnson Shut-Ins

About this map

Johnson Shut-Ins State Park anchors this landscape in the late 1960s, where the East Fork Black River carves through the ancient geology of the St. Francois Mountains. This era is defined by the massive engineering of the Taum Sauk Pumped-Storage Hydroelectric Powerplant, featuring the Upper Reservoir atop Proffit Mountain and the Lower Reservoir below. The map captures a transition between industry and recreation, with the Taum Sauk Nature Museum and the rugged Taum Sauk Trail drawing visitors to the same heights once dominated by timber and mining.
