About this map

The Umatilla River valley serves as a critical transportation corridor in this 1966 survey, where the Pacific Union and Union Pacific railroads trace the winding riverbed. The settlement of Barnhart sits at a narrow point in the valley, while Rieth occupies the junction where Birch Creek joins the main river system. The landscape is defined by dramatic elevation changes, notably along the prominent Rieth Ridge and the deep incision of Coombs Canyon to the south.

Modern infrastructure of the mid-1960s is layered over this traditional river-and-rail route, including the 80n highway and a Radio Vortac Facility. Industrial and agricultural activity is evidenced by a Quarry near the river and Storage Bins on the plateau. These features illustrate the area's evolution from a purely rail-dependent landscape to one supporting highway transport and aviation technology during the mid-twentieth century.
