The Willamette River defines the landscape of this area, winding between the borders of Yamhill, Polk, and Marion counties. Along its banks, numerous bars and islands such as Windsor Island and Beaver Island illustrate the river's historical shifting course, creating unique features like Lambert Slough and Mission Lake. On the eastern shore, the expanse of French Prairie meets the water, while the Eola Hills and Jerusalem Hill rise to the west, providing a varied topography that has shaped local settlement patterns.
