About this map

Pend Oreille River anchors this corner of the Pacific Northwest, captured during the late 1960s just as the Boundary Dam transformed the landscape with its reservoir. The map reveals an intensive mining corridor along the river's banks, including the Josephine Mine, Lucky Strike Mine, and the Pend Oreille Mine, illustrating the region's industrial dependence on lead and zinc extraction. These workings are concentrated near the southern boundary, where Tailings and various Drill Hole markers indicate the scale of subterranean activity.

Contrasting this heavy industry is the recreational and preserved wilderness of the Colville National Forest and the Salmo-Priest Wilderness. In the north, the international boundary with Canada is marked by a U S Customs post and the subterranean wonder of Gardner Cave within Crawford State Park. The terrain shifts from the high peaks of Dolomite Mtn and Crowell Mtn to the water-level Crescent Lake Campground, showing a landscape managed for both extraction and conservation.
