Summerfield Ridge dominates this northern Oregon landscape, where the high terrain of Morrow County transitions into the protected timberlands of the Umatilla National Forest. The map, field checked in the late 1960s, documents a complex network of drainage canyons and upland springs that define the local topography. Major watercourses like Rhea Creek and the Balm Fork are fed by numerous family-named landmarks including Sperry Spring, Smith Birch Spring, and Skinner Spring.
