About this map

Clark Fork sits at the heart of this Idaho-Montana borderlands survey, where the Northern Pacific railroad tracks trace the northern bank of the Clark Fork river. The landscape is defined by its industrial and infrastructure projects at the start of the 1950s, most notably the Cabinet Gorge Dam and the nearby State Fish Hatchery. Significant blue hatching on the map identifies the specific areas designated to be submerged by the completion of the Albeni Falls Dam, providing a precise record of the valley floor before its permanent alteration.

Mining activity remains a prominent feature of the local economy and geography, with the Hope Mine, Whitedelf Mine, and Lawrence Mine all located north of the primary settlement. The survey also captures rural civic landmarks including the River Echo Sch (Aband) and the Clark Fork Ranger Sta. This territory is heavily forested, partitioned between the Kaniksu National Forest, Kootenai National Forest, and Coeur d'Alene National Forest.
