About this map

Lake Oahe dominates the eastern edge of this landscape, where the waters of the Missouri River have transformed the riverine environment of Stanley and Sully Counties. The terrain is defined by deeply carved drainages such as Chantier Cr and Snake Cr, which cut through the high plains toward the reservoir. Local transportation is represented by rural routes like Agency Creek Rd and Snake Creek Rd, which provide access to more remote locations including the Princes Ranch and the W L Thompson Airport. This map illustrates the intersection of mid-century infrastructure and long-standing ranching tradition, showing how Gumbo Rd and SD 1806 navigate the intricate topography of the Missouri breaks. The presence of Deep Cr and Red-Woman Cr further highlights the complex network of seasonal and permanent watercourses that have historically shaped land use in this part of South Dakota.
