Monmouth and Independence anchor this 2024 landscape in Polk County, where the agricultural flats of the American Bottom meet the shifting curves of the Willamette River. The area is a dense network of water management and education, home to Western Oregon University and numerous irrigation features like Garrison Reservoir and Nisly Reservoir. Small settlements such as Parker, Buena Vista, and Modeville dot the rural reaches, connected by historic routes like Old Fort Rd and Corvallis Rd.
