The South Yamhill River valley serves as the central corridor for this region, where the timber industry and agriculture have long shaped the landscape. Evidence of industrial operations is visible at the Pacific Plywood Log Pond near Willamina, a town situated at the confluence of Willamina Creek and the river. To the east, the city of Sheridan is the primary population center, positioned where Mill Creek meets the South Yamhill.
