2015 Map of Coal Springs NW

About this map

Big Meadow Cr and its tributaries carve a subtle network of drainages across this portion of Perkins County, revealing a landscape defined by seasonal watercourses and the open range of South Dakota. The drainage systems of Thunder Butte Cr and Duncan Cr dominate the southern and eastern portions of the quadrangle, illustrating the natural flow patterns toward larger basins beyond the map boundaries. Human infrastructure is minimal, represented primarily by Rolling Hills Rd, which provides a horizontal corridor through the central hills. This survey documents the sprawling Public Land Survey System divisions, including Township t18n r15e and Township t17n r16e, showcasing how early land-office grids remain the primary organizational framework for this remote prairie terrain into the twenty-first century.
