2011 Map of Rattlesnake Mountain

About this map

Rattlesnake Mountain dominates the landscape of this region in Lewis and Clark County, where cattle ranching and modern roadways intersect with high-altitude terrain. The presence of the Old Synnes Ranch and Old Thorne Ranch indicates a history of family-held agricultural land in the valleys south of the peaks, while Payne Camp suggests seasonal or specialized utility in the northern reaches. The area is defined by significant drainage systems including Clark Creek and Willow Creek, which carve through features like McLeod Basin. This topography is shaped by water and gravity, evidenced by the named Diamond Spring Gl and the steep descent of Sawmill Gulch. Modern connectivity is provided by routes such as Gates of the Mountain Rd and Toehead Rd, which traverse the lower elevations between Copper Butte and the surrounding ridgelines.
