1966 Map of Evergreen Ridge

USGS Topo · Published 1968

About this map

Evergreen Ridge and the broad basalt plateaus of Grant County dominate this mid-century survey of Central Washington's arid interior. The landscape is defined by the massive engineering projects of the Columbia Basin Project, characterized by an extensive irrigation network including the Aqueduct, a large Siphon, and the Evergreen Pumping Plant. These features facilitated the movement of water from the Columbia River to the agricultural lands above the coulees.
