About this map

The Pend Oreille River anchors this mountainous corridor of the Pacific Northwest, just south of the border between Canada and the United States. The landscape is dominated by the industrial infrastructure of the Boundary Dam and its associated substation, which harness the river's power as it flows through the narrow canyon. To the west, the subterranean reaches of Gardner Cave within Crawford State Park provide a geological focal point, while the surrounding lands are managed by the Colville National Forest and Kaniksu National Forest.

Resource extraction and backcountry recreation define the area's development. Mining sites such as the Morning Mine, Grandview Mine, and Josephine Mine are clustered in the southern portion, reflecting the region's mineral history. Small enclaves like a Trailer Park and the Riverside Mine settlement appear alongside the river, while the eastern heights reach into the Salmo-Priest Wilderness, marked by distinctive terrain features like Slumber Peak and Confusion Ridge.
