2021 Map of Bog Creek

About this map

The Jumpoff dominates the central landscape of this Harding County region, where the high plains break away into a complex network of drainages and buttes. This modern survey illustrates a watershed divide of the northern plains, showing the headwaters and tributaries of two major river systems. To the north, the S Fork Grand River and its feeders like Faulkner Cr and Bog Cr carve through the terrain, while the southern portion of the map is defined by the N Fork Moreau River and the East Short Pine Hills. Human impact is sparse, centered on managed water resources like the Gilbert Number Two Reservoir and the transit corridor of Mackey Rd. The topography reveals the intricate erosion patterns of Chalk Butte Draw and the Sand Coulee, providing a clear picture of the arid, wind-swept geography of South Dakota's northwest corner.
