About this map

Lake Koocanusa dominates the central valley of this 2020 landscape, a vast reservoir formed by the damming of the Kootenai River. The map captures the significant elevation changes between the water level and the surrounding peaks of the Purcell Mountains, including the namesake Alexander Mountain and Fleetwood Point. These high ridges, such as Rainy Divide and Souse Ridge, define the drainage patterns for numerous mountain streams like Little Jackson Cr and Souse Cr.

Modern infrastructure is represented by the David Thompson Bridge, which spans the Kootenai Narrows to provide access between the rugged east and west banks. The majority of the territory is managed as the Kootenai National Forest, where a network of forest development roads, including Natl Forest Develop Road 334 Rd, snakes through the timbered slopes. Notable landmarks like Yarnell Island and Big Bend mark the winding path of the reservoir through this corner of Lincoln County.
