About this map

Paradise Valley marks the northern extent of this mid-1960s survey, where the relatively level terrain of the valley floor meets the dense woodlands of the Kaniksu National Forest. The landscape is defined by its network of watercourses and high ridges, including Twentymile Creek and Grouse Creek, which drain the surrounding peaks. Human activity is evidenced by a complex system of transportation routes, including a pipeline corridor, several pack trails, and jeep trails that navigate the high country.

A Lookout Tower on Black Mountain stands as a prominent landmark for fire observation, while named summits like Twentymile Peak and Bald Eagle Mtn indicate the high-elevation points of interest. Movement through the peaks is dictated by natural gaps such as Twentymile Pass and Kelly Pass. To the southwest, Beaver Lake and Sand Mtn provide further topographic definition near the Boundary and Bonner County line.
