1968 Map of Cannon Ball NW

About this map

The Cannonball River meanders through the southern portion of this landscape, marking a significant topographical and jurisdictional divide. To the south, the Standing Rock Indian Reservation Boundary borders the small settlement of Solen, while the northern reaches are dominated by the Fort Rice Military Reservation. The geography is defined by the transition of the river valley toward Lake Oahe, where the map notes a normal pool elevation of 1608 feet. This 1960s survey documents a rural area where transportation history is visible in the Old Railroad Grade following the river's path. High ground is punctuated by landmarks such as Castle Butte, overlooking the intricate drainage system of North Branch Cantapeta Creek as it feeds into the Missouri River Basin's regulated waters.
