1966 Map of Mission

About this map

The Umatilla River valley serves as the central corridor of this 1960s landscape, which is heavily shaped by the administrative and cultural presence of the Umatilla Indian Reservation. The community of Mission acts as a primary hub, containing the Indian Agency Hdqrs and significant local landmarks like the Indian Ceremonial Ground Cem. Transport and utility infrastructure is prominent, with the Union Pacific and Burlington Northern railroads following the river's path, while an Old Indian Treaty Boundary and a Pipeline cut across the grain of the hills.
