Polk County elevation and terrain tools
Willamette Valley • County seat: Dallas
Polk County spans the west side of the middle Willamette Valley, from river bottomland across from Salem to the Eola Hills and the Coast Range. Dallas sits at the foot of those forested ridges, which rise steadily toward the western edge of the county.
