Speare Canyon and the drainage systems of southern Umatilla County define this high desert landscape south of the Umatilla River. The map documents a sparsely populated rural area primarily organized by a geometric grid of county roads that navigate the complex topography of deep canyons and plateaus. Historical movement through these corridors is evident in the winding path of Speare Canyon Rd and Mud Springs Canyon Rd, which follow the natural contours of the land. Other routes like Co 1383 Rd, Co 1394 Rd, and Blanchet Ln provide access to the expansive agricultural or grazing lands that characterize this part of eastern Oregon. This 2011 survey serves as a detailed record of land use and rural infrastructure in the high country before modern developments altered these traditional rural corridors.
