1968 Map of Summersville NE

About this map

Spring Valley defines the topography of this Shannon County landscape in the late 1960s, a region where deep hollows and karst features dominate the terrain. The presence of the Forty Acre Sinkhole and numerous dry valleys like Peter Cave Hollow and Pipestem Hollow illustrate the complex subsurface drainage systems typical of the Missouri Ozarks. Along the southern edge of the map, the Ozark National Scenic Riverways boundary reflects the transition of this area into a protected river corridor.
