1964 Map of Duncan

About this map

Meacham Creek carves a deep valley through the Blue Mountains, serving as the primary corridor for the Union Pacific railroad. This 1964 survey (revised 1983) illustrates the remote character of northeastern Oregon, where the tiny settlements of Gibbon and Duncan anchor a landscape defined by sharp ridges and seasonal springs. The territory is largely managed as the Umatilla National Forest, with the Umatilla Indian Reservation Boundary cutting across the northwestern corner. Notable landmarks like the Duncan Guard Station and named terrain such as Black Canyon Butte and Horse Heaven Ridge reflect the area's history of forestry and livestock grazing. Numerous named water sources, including Little Squaw Spring and Buck Spring, suggest the critical importance of water access in this high-elevation environment.
