Southern Benton County

Southern Benton County extends from Corvallis to just south of the town of Monroe (toward the southeast) and the northern part of Lobster Valley south of the town of Alsea (toward the southwest). The eastern boundary is the Willamette River. Parts of Benton county to the west of Highway 34 (e.g., Marys Peak) are covered in the Middle Tier section of this website. The map below does not cover the southwest corner of the county (which includes the town of Alsea).
