2024 Map of Dead Boy Divide

About this map

Dead Boy Divide serves as the central geographic landmark for this region of Carter County, separating the drainages of Dead Boy Creek to the south from Buffalo Creek and Lone Tree Creek to the north. The landscape is defined by an extensive network of water management features, including a series of reservoirs named for tribal nations such as Apache Reservoir, Navaho Reservoir, Sioux Reservoir, and Gros Ventre Reservoir. This reliance on contained water sources like Lone Tree Reservoir Number One and Lone Tree Reservoir Number Two underscores the challenges of ranching and agriculture in this corner of Montana. In the northern reaches, Soda Lakes and Fresh Water Draw provide further evidence of the varying mineral and water quality across the terrain, while routes like Chalk Buttes Rd and Lone Tree Rd remain the primary corridors through the open range.
