2011 Map of Coombs Canyon

About this map

Coombs Canyon defines the drainage and road network of this portion of Umatilla County, where the landscape is marked by isolated rural outposts and a grid of access roads. The settlement pattern is sparse, centered on sites like the Cross Ranch and the reliable water source of Crazy John Spring to the west. Evidence of the region's ranching and transit history is visible in the naming of secondary routes such as Coombes Canyon Rd and Redwine Rd, which navigate the draws and plateaus. To the north, the Rieth Bridge serves as a key crossing point, while the southern reach of the quadrangle is defined by a series of straight-line section roads including Heartbreak Rd and Webb Rd. The map illustrates a rural interior where geographic features and local property lines dictate the human footprint.
