2020 Map of Rocky Ridge South

About this map

The Little Missouri National Grassland dominates this portion of Slope County, North Dakota, where the High Plains transition into a broken network of drainages and seasonal watercourses. The local hydrology is defined by a series of north-flowing tributaries including First Cr, Second Cr, and Third Cr, which carve through the undulating terrain. A significant landmark in the northern section of the map is Rocky Ridge, a topographic high point that overlooks the surrounding prairie. Evidence of the region's ranching and natural resource landscape appears in the presence of Big Spring, a vital water source in this semi-arid environment. The sectional layout is clearly defined by the Public Land Survey System grid, with 56th St SW providing one of the few formal transportation corridors through this expansive landscape of public and private grazing lands.
