About this map

The Continental Divide winds through the high ridges of the Beaverhead Mountains, defining the border between Idaho and Montana. This high-altitude landscape is characterized by prominent summits such as Red Conglomerate Peaks and the massive Heart Mtn, which reaches over ten thousand feet. The transition between the Beaverhead National Forest to the north and the Targhee National Forest to the south reveals a complex drainage system, where dozens of canyons like Black Canyon and Poison Gulch feed into major watercourses.

Edie Ranch serves as a lone human waypoint in this expansive terrain, situated near the headwaters of Edie Creek. The presence of Antelope Lakes and named springs like Robertson Spring and Big Spring highlight the critical importance of water sources in this high-country environment. Navigational landmarks such as the Buckboard trail suggest the traditional routes used to traverse these steep divides before modern development.
