The Calapooya Divide serves as a prominent geographic spine in this 2017 study of the terrain along the Lane County and Douglas County border. This is a landscape defined by significant elevations and a dense network of watercourses, including the Big River and Little River. Human impact is etched into the topography through a system of timber and access roads such as London Weyerhaeuser and Big River Road, which navigate the steep rises of Harness Mountain and Cinnabar Mtn. The map preserves several small-scale historical markers, notably the Bemis Cem and Rouse Bridge near the northern boundary. These features, along with family-named peaks like Akerson Butte and Hobart Butte, provide essential anchor points for genealogists and local historians tracing the heritage of this timber-rich region of the Pacific Northwest.
