2024 Map of Rustler Divide

About this map

Custer National Forest dominates this landscape in Montana's far southeastern corner, where the high ridge of Rustler Divide separates several critical drainage basins. This modern topographic study reveals a complex network of springs and reservoirs that support life and livestock in this arid environment, including Abel Reservoir, Dead Horse Reservoir, and the trio of Mobray Reservoirs. The presence of numerous named springs, such as Coal Bank Spring and Jack Spring, suggests the vital importance of water sources across the forested slopes of the Long Pines area. A dense system of forest roads and trails, such as Devils Canyon Trl and Maverick Gulch Trl, provides access through the backcountry between Grassy Butte and Stormy Butte, mapping out the contemporary management and recreational use of these public lands.
