About this map

Kaniksu National Forest defines this high-elevation landscape in the mid-1960s, dominated by a series of prominent peaks and ridges. The terrain is marked by the central massif of Clifty Mountain and Iron Mountain, with the Boulder Mine situated on the western slopes above Boulder Creek. This area serves as a critical watershed, where numerous drainages such as Pinochle Creek, Treble Creek, and Hunt Girl Creek carve deep into the mountainsides.

Logistics across this steep environment relied heavily on a network of primitive routes, including the Kelly Poker Pass Trail and the Katka Peak Trail. Along the southern margin, the boundary between Boundary and Bonner Counties crosses near Middle Mtn, illustrating the jurisdictional lines drawn through the Kootenai National Forest. The map documents a period of remote resource exploration and forest management before modern road development altered the access patterns of these northern Idaho highlands.
