Corvallis and Philomath anchor this 2024 landscape at the confluence of the Willamette River and Marys River. The city’s identity as a center of education and governance is clearly visible through the sprawling Oregon State University campus and the central Benton County Courthouse. The mapping detail captures a complex river system characterized by numerous side channels and islands, including Stahlbusch Island and Kiger Island, alongside smaller waterways like Dunawi Creek and Oak Creek.
