2020 Map of Shirley

About this map

The Yellowstone River defines the western edge of this Custer County landscape, where the settlements of Shirley and Bonfield sit along the river's eastern banks. This area showcases the transition from riparian commerce to the upland coulees and drainages typical of the region. The Kinsey Main Canal mirrors the river's path, indicating a managed water system essential for local agriculture. To the east, the terrain is carved by numerous seasonal drainages, including Dead Horse Cr, Miles Cr, and Charlie Cr, which flow through the dissected breaks toward the river valley. In the southern portion of the quadrangle, McFarland Reservoir and the split branches of Dixon Cr and N Dixon Cr highlight the reliance on small-scale water management in the drier Montana interior. Modern transportation corridors like W Old Highway 10 and Diamond Ring Rd provide access to these remote ranching and irrigation districts.
