About this map

Clark Fork sits at the heart of this landscape where the river meets the vast waters of Pend Oreille Lake. The area is defined by the braided channels of the North Fork, Middle Fork, and South Fork, which wrap around Derr Island before entering the lake. The terrain rises sharply from the riverbanks into the Kaniksu National Forest, reaching peaks like Cougar Peak and Bee Top Mountain.

Resource extraction and research characterize the local economy and land use during the late 1980s. The map identifies several significant mining operations, including the Whitedelf Mine, Hope Mine, and Lawrence Mine, while the University of Idaho (Clark Fork Field Campus) and a Fish Hatchery point to the region's importance for environmental study. The Pend Oreille State Wildlife Management Area covers much of the shoreline, preserving the marshy habitat of Denton Slough.
