The Tualatin River meanders through the heart of this Washington County landscape, defining the boundaries of agricultural and residential life south of Hillsboro. The terrain transitions from the low-lying Jackson Bottom to the rising slopes of the Chehalem Mountains and Laurel Ridge. The infrastructure of the area is anchored by several river crossings, including Rood Bridge and Scholls Bridge, which connect small communities like Scholls, Midway, and Farmington.
