About this map

Clark Fork winds through a narrow canyon floor, serving as the primary corridor for regional transit and settlement. The small communities of Piltzville and Turah are concentrated along the riverbanks, where the topography levels out before ascending sharply into the high country. This modern topographic study reveals a landscape defined by dramatic vertical relief, from the heights of Bonner Mtn and Olson Peak to the drainages of Crystal Creek and Donovan Creek.

To the south, the Lolo National Forest encompasses the northern reaches of the Sapphire Mountains, where Moccasin Ridge separates the winding Greenough Creek from the high-elevation trails. The map documents an intricate network of forest and local roads like Chumrau Loop and Slide Rock Dr, which provide access to the various gulches, including Bear Gulch and Heyers Gulch, that feed into the valley below.
