2024 Map of Shirley

About this map

The Yellowstone River flows through this corner of Custer County, shaping a landscape defined by its vital water sources and early agricultural infrastructure. In this area, the Kinsey Main Canal runs parallel to the river's western bank, highlighting the engineering required to support ranching and farming in the region's semi-arid environment. The small settlements of Shirley and Bonfield serve as the primary local hubs, connected by the historic route of W Old Highway 10. Numerous drainages, including Dead Horse Creek, Cottonwood Creek, and Charlie Creek, carve out the surrounding terrain. Local transportation is further detailed through named thoroughfares such as Lower Rd and the evocatively named Diamond Ring Rd, providing a clear view of the rural road network used by generations of Montana residents.
