1982 Map of Millboro

About this map

Millboro sits near the winding course of the Keya Paha River in this survey of the borderlands between Tripp County, South Dakota, and Keya Paha County, Nebraska. The landscape is defined by a network of seasonal drainages, including Willow Creek, Lost Creek, and Cottonwood Creek, which carve through the plains. Local infrastructure in the early 1980s is centered on small-scale resource extraction and rural landmarks, such as the Gravel & Sand Pit and a local Cem. The presence of the Roadside Park along the highway and the Rames water feature reflect the region's ranching and transit character. This map captures the township and range divisions near the state line, providing a precise record of property boundaries and local landmarks during a period of steady agricultural use.
