The S Yamhill River winds through this 2014 landscape, marking a critical transition between the forested highlands of the Siuslaw National Forest and the agricultural valley. Small settlements such as Midway and Boyer serve as focal points along the Hebo Rd corridor, while the eastern edge of the map includes a portion of Grand Ronde. The complex political geography of the Oregon Coast Range is on display here, as five different counties—Yamhill, Tillamook, Polk, and Lincoln—converge in a series of boundaries that follow the ridgelines and watercourses.
