About this map

Onion Mtn serves as a central high point in this 2020 survey of the Siskiyou National Forest, where steep drainages and isolated springs define the terrain. The eastern edge of the map is bordered by the Rogue Wild and Scenic River, accessible via Riverbanks Rd. This modern map details the intricate network of forest service and bureau roads, including BLM Rd 35-7-17 and Shan Creek Rd, which provide access to localized landmarks like Taylor Creek Falls and the Walters Creek Interpretive site.

Water sources are remarkably dense across this landscape, from high-elevation points like Annie Spring and Rattlesnake Spring to the многочисленные gulches that feed the larger creek systems. These include named features such as Midnight Gulch, Newt Gulch, and Pollard Gulch. For researchers, the map provides a clear look at the Public Land Survey System divisions, marking the junctions of multiple townships and ranges within Josephine County.
