2014 Map of O'Brien

About this map

The community of O'Brien serves as a central hub for this portion of the Illinois Valley, where the Redwood Hwy facilitates travel through the southwestern Oregon landscape. The area is defined by the convergence of the West Fork Illinois River and its numerous tributaries, which have carved a complex system of gulches such as French Flat, Sailor Gulch, and Butcher Gulch. Local industry and infrastructure are represented by the Illinois Valley Airport and the Rough and Ready Mill Pond Dam along Rough and Ready Creek. Much of the territory is contained within the Siskiyou National Forest, characterized by prominent elevations like Lone Mtn and Bearcamp Ridge. For those examining land use and local hydrology, the map details many small watercourses including Leuzinger Cr, Parker Cr, and Mendenhall Cr, alongside man-made features like Esterly Lakes and Logan Cut.
