2023 Map of Cottonwood Creek

About this map

The Continental Divide crests along the Beaverhead Mountains on this survey, marking the high-altitude boundary between Idaho and Montana. The terrain is defined by a series of significant drainages including Eighteenmile Creek, Pass Creek, and the headwaters of Cottonwood Creek. These waters flow through the rugged public lands of the Beaverhead National Forest and Targhee National Forest, eventually descending toward the Lemhi Valley. The landscape is etched with historical routes and trails, most notably the Continental Divide National Scenic Tr, which follows the state line. Evidence of early land management and water access is seen in named features like Breazeale Spring and Walters Spring, while remote access is provided by primitive tracks such as 18 Mile Rd and Willow Creek Rd.
