About this map

Thunder Butte Cr winds through the southern reaches of this Ziebach County landscape, carving a dendritic drainage pattern into the prairie. This 2021 survey by the U.S. Geological Survey illustrates a contemporary view of the region's hydrography, where seasonal waterways like Beaver Trap Cr and W Beaver Trap Cr converge. The terrain is defined by the Public Land Survey System grid, including townships t16n r18e and t15n r19e, which organize the open country. Thunder Butte Rd serves as the primary artery through this sparsely developed area, reflecting the enduring rural character and ranching infrastructure of north-central South Dakota in the early 21st century.
