2012 Map of Millboro

About this map

Millboro sits as the central settlement in this portion of Tripp County, South Dakota, positioned just north of the winding Keya Paha River. The surrounding landscape is defined by a dendritic drainage pattern where several significant watercourses, including Willow Cr and Lost Cr, converge toward the river valley. A strictly organized grid of rural roads, such as 311th Ave and 299th St, segments the territory, reflecting the long-established section-line surveying traditions of the Great Plains. To the east, the course of Cottonwood Cr provides a prominent natural boundary in an otherwise geometrically ordered agricultural landscape. This survey demonstrates the persistence of small rural hubs like Millboro within the vast expanses of the northern prairie.
