Ledges State Park anchors the northeastern corner of this 1960s landscape, where the deeply carved sandstone cliffs meet the winding Des Moines River. This era captures the transition of the river valley during the development of the Saylorville Reservoir, showing the anticipated normal pool elevation 833. The map documents a blend of conservation and institutional land use, including the State Game Farm and the extensive grounds of the Woodward State Hospital to the south.
