2017 Map of Harrold NW

About this map

Medicine Knoll Cr winds through the northwest corner of this prairie landscape, defining the local hydrology in an area otherwise characterized by intermittent wetlands and seasonal basins. Located along the eastern edge of Sully County, the map documents the Sully Co Hyde Co boundary as it stood in 2017. The terrain is organized by a grid of rural roads and section lines, including Co Rd 649 and 321st Ave, which provide access to the vast agricultural allotments and cattle grazing lands of central South Dakota. The survey highlights a sparse settlement pattern typical of the High Plains, where human presence is primarily marked by long straightaways such as 185th St and 189th St. The mapping of these land divisions offers a clear view of the modern rural infrastructure and natural drainage patterns in the Missouri Plateau region.
