Umatilla National Forest encompasses much of this high-elevation landscape, where the boundary between Morrow Co and Umatilla Co runs north-to-south through a network of clearings and drainages. The area is defined by its numerous high meadows, including Matlock Prairie, Balsinger Prairie, and Kenny Prairie, which likely served as seasonal grazing grounds or transit points for early ranchers and travelers. This terrain is carved by complex water systems, notably Butter Creek, Swale Creek, and Matlock Creek, which originate near landmarks like Arbuckle Mtn and Matlock Hill.
