1957 Map of Copperfield

About this map

Brownlee Dam and its impending impact on the river canyon define this mid-century survey along the border of Idaho and Oregon. Blue hatching indicates the specific areas of the Snake River canyon slated to be submerged as the dam reached its spillway elevation, a transformation that would soon alter the landscape near The Oxbow. This era of hydroelectric development is documented alongside rural infrastructure including the Oxbow Sch and Brownlee Sch, as well as a Microwave Relay Station on the high ridges.
