1992 Map of Boundary Dam

About this map

The Pend Oreille River carves a deep path through the northern reaches of the Colville National Forest in this early 1990s record of the Washington-Canada borderlands. Anchoring the northern end of the map is the massive Boundary Dam, where industrial infrastructure like substations and a gaging station contrast with the primitive terrain of Z Canyon. This era shows a landscape defined by heavy mining activity, particularly near the southern reach of the river where the Pend Oreille Mine, Grandview Mine, and Josephine Mine are situated near the community of Metaline.
