About this map

Bitterroot National Forest and Salmon National Forest meet along the high ridges of the Montana-Idaho border in this 2017 survey. The landscape is defined by massive peaks like Allan Mtn and Rocky Mtn, separated by deep drainages such as Hughes Creek and Ditch Cr. This area preserves a primitive character, with access provided by the Divide NRT and Hughes Creek Rd, which snakes through the valley past Salzer Bar.

The presence of scattered landmarks like Ax Park and high-elevation water bodies including Burrell Lake and Allan Lake suggests a region primarily used for timber, grazing, and recreation. Natural water sources are named throughout the terrain, from Indian Spring to the higher Butcherknife Spring near Butcher Knife Ridge. This map captures the remote transition from Ravalli Co, Montana, into the rugged northern reaches of Idaho.
