About this map

Targee National Forest encompasses the western portion of this high-elevation landscape in Clark County, defined by a complex network of canyons and gulches. The terrain is notably marked by geological features like Maud Mtn and Horse Ridge, which divide the drainages of Crooked Cr and Warm Springs Cr.

A system of remote roads, including Myers Creek Rd and Chandler Canyon Rd, provides access through the deeply cut topography. Several water sources are vital to the area's geography, such as Shamrock Spring and Lower Crystal Spring. The map documents a rugged interior with significant features like Devils Gap and Black Horse Canyon, illustrating the challenging environment of the Idaho backcountry.
