1967 Map of Boundary Dam

About this map

Pend Oreille River flows north toward the Canadian border, dominating this 1967 survey of a landscape defined by industry and conservation. The map captures the infrastructure of the Boundary Dam, including the Vista House, Gaging Station, and various Substations near the river's canyon. Extensive mining operations are documented throughout the hills, from the large Pend Oreille Mine and Josephine Mine in the south to numerous Drill Hole locations and the Lucky Strike Mine along Slate Creek.
