The Calapooia River floodplain dominates this 2014 survey, where a complex network of sloughs and ditches supports the agricultural landscape of Linn County. The settlement of Shedd and the northern edge of Halsey anchor the western corridor along Or-99e, while the eastern portion reveals the prominent elevations of the Powell Hills and Ward Butte. These basaltic outcroppings rise sharply from the flat valley floor, providing distinct landmarks such as Saddle Butte and Bunker Hill.
