1959 Map of Prairie City

About this map

Prairie City anchors this 1950s survey of eastern Grant County, where the valley of the John Day River meets the high elevations of the Malheur National Forest. The map reflects a dual economy of ranching and natural resource extraction, with the Oxbow Ranch and Ray Ranch situated near the irrigation network of the Ditch and Dixie Creek. Timber and mineral interests are evident at the local Mill and Maude Thompson Mine, while the infrastructure of the era is captured through the Landing Strip and a Sewage Disposal site.
