About this map

Kootenai National Forest dominates this section of the Purcell Mountains in northwest Montana, where a network of forest service roads and backcountry trails facilitates access to the high-elevation terrain. The Pacific NW National Scenic Trail winds through the landscape, passing beneath Boulder Mtn and Purcell Summit. The drainage patterns here are complex, defined by the Little North Fork Big Creek and the numerous forks of Big Cr and Good Cr.

Remote water features like the Boulder Lakes are tucked between steep ridgelines such as Cliff Point / Thirsty Mountain. Human activity is primarily visible through specialized infrastructure like the East Pipe / Big Creek Snowmobl route and named local landmarks including Bunker Hill and Knife Gulch. The map captures the area's essential character as a managed wilderness area where topographic features like Pinto Point serve as critical navigation markers.
