About this map

Custer National Forest encompasses this high-plains landscape in Carter County, Montana, where the terrain is defined by dramatic geological breaks and isolated water sources. The Rustler Divide runs through the central portion of the map, separating drainage systems like Rustler Canyon and Devils Canyon. This area is characterized by the Long Pines landform and a complex network of springs and man-made catchments vital for ranching and wildlife in an arid environment.

Water management is prominent throughout the survey, evidenced by numerous named improvements such as LLW Reservoir, Etta Reservoir, and Mobray Reservoir Number 2. These are fed by a high density of small springs, including Coal Bank Spring, Jack Spring, and Grasshopper Spring. The landscape transitions from the higher elevations of Grassy Butte and Stormy Butte down into carved features like Maverick Gulch and Lampkin Gulch, while Forest SVC RD 117 provides the primary transit artery through the timbered hills.
