2020 Map of Boulder Lakes

About this map

Kootenai National Forest dominates this section of northwestern Montana, where the Purcell Mountains rise to prominent heights such as Boulder Mtn and Thirsty Mtn. This high-altitude landscape is defined by its drainages, including Porcupine Cr in the north and the complex network of Big Cr and its tributaries like the Little N Fork Big Creek to the south. The mapping of the Pacific NW National Scenic Trail as it traverses the ridges near Purcell Summit highlights the importance of modern recreational corridors within the traditional timber and resource lands of Lincoln County. Local topography is punctuated by steep features such as Knife Gulch and the high basin containing Boulder Lakes, while the presence of Bunker Hill suggests a history of local land naming in this mountain range.
