2017 Map of Rustler Divide

About this map

Custer National Forest dominates the high-country landscape of southeastern Montana, centered on the prominent Rustler Divide that separates various drainages within the Long Pines region. This modern topographic record reveals a sophisticated water management network essential for livestock and wildlife in a semi-arid environment, marked by numerous developed points such as Mobray Reservoir Number 2, Etta Reservoir, and the L-W Reservoir. The terrain is deeply incised by drainages like Devils Canyon and Halbert Gulch, while distinctive high points like Stormy Butte and Grassy Butte provide navigational landmarks. Numerous named water sources, including Lantis Spring, Burditt Spring, and South Carter Spring, are distributed across the township sections, tracing the vital importance of groundwater. Forestry access is maintained via the U S Forest Rd, which winds through the complex topography of Rustler Canyon and Spring Canyon.
