2017 Map of Monida

About this map

Monida sits at a critical high-altitude junction where the Continental Divide meets the boundary between Montana and Idaho. This 2017 survey details the rugged crossing at Monida Pass, a historically significant gap that facilitates travel between the Centennial Valley to the north and the expansive timberlands of the Targhee National Forest to the south. The landscape is defined by its water systems, from the marshy northern reaches of the Lima Reservoir to the branching headwaters of Beaver Cr and Modoc Cr. Evidence of the area's ranching and transit heritage remains visible through the network of local routes like Grover Ranch Rd and the path of Old Hwy 91, which parallel the modern interstate corridor. High points such as Pinetop Hill and the Knoll provide geographic context for this high-mountain transit hub.
