2017 Map of Bison Bone Reservoir

About this map

Bison Bone Reservoir and the surrounding drainage systems define this landscape in Phillips County. This 2017 survey details a remote portion of north-central Montana dominated by seasonal waterways and small-scale water management. The network of creeks, including Beauchamp Cr, Dry Fork Cr, and Trine Cr, indicates a terrain shaped by erosion and cattle-country hydrology. Human presence is sparse, anchored primarily by the east-west corridor of Dry Fork Rd. Smaller water features like Pep Reservoir and a Private Reservoir located near Cline Cr reflect the practical adaptations of ranching life in an arid environment. The map provides a clear look at the public land survey system divisions across multiple townships, including T24N R27E and T25N R26E, which continue to dictate property and land use in this open range.
