About this map

The Illinois River and its numerous tributaries dominate this 1980s landscape in Josephine County. The settlement of O'Brien sits at the junction of O'Brien Creek and the river, while the historic mining locale of Waldo is positioned further southeast near the Waldo Hill terrain. The map reveals an area defined by hydraulic and placer mining history, evidenced by features like the Esterly Mine, Logan Cut, and Gravel Cut.

Large portions of the territory fall within the Siskiyou National Forest and the Rough and Ready Creek Forest Wayside State Park. The drainage network is complex, featuring named gulches such as Sailor Gulch, Fry Gulch, and Allen Gulch. Topographical landmarks including Bearcamp Ridge, Gilligan Butte, and Indian Hill provide significant orientation for those studying the physical geography and land-use patterns of this corner of southwest Oregon during the late twentieth century.
