About this map

Stony Buttes anchors the central landscape of this West River South Dakota survey, serving as a prominent landmark above the surrounding drainage networks. The terrain is defined by a complex system of draws and seasonal waterways, including Stony Buttes Draw and Seven D Draw, which channel into larger basins. This area on the Pennington County and Haakon County line reflects a rural, high-plains environment where water management and access are dictated by the paths of Mixes Food Cr and Deep Cr. Small-scale infrastructure like Quinn-Pedro Rd and Oconnell Rd provide the primary transit through these sections, illustrating the sparse settlement pattern typical of the region's ranching and agricultural history. The convergence of E Fork Deep Cr and Ash Cr further illustrates the hydrological importance of this specific quadrangle within the wider Missouri River watershed.
