Ankeny National Wildlife Refuge dominates the landscape of southern Marion County, preserving a complex system of wetlands and bottomlands where the Willamette River and Santiam River converge. This survey details a transition from the rolling terrain of the Salem Hills and Jackson Hill down to the fertile American Bottom. The presence of the Sidney Power Ditch and Sidney Irrigation Ditch Trl near the settlement of Sidney reflects the long-standing water management required for the region's agricultural productivity.
