The Umatilla River valley defines the character of this 2011 survey, cutting through the landscape between the elevated Rieth Ridge and the southern drainage of Coombs Canyon. Small settlements like Barnhart and Campbell are situated near the river, reflecting the historical importance of the watercourse for transportation and agriculture in this portion of Umatilla County. The area is characterized by a network of established local roads, including Stage Gulch Rd and Yoakum Grade Rd, which connect the upland plateaus to the river basin.
