USGS Topo · Published 2023About this map
The West Fork Illinois River and its many tributaries, including O'Brien Creek, define the geography of the Illinois Valley in Josephine County. The settlement of O'Brien sits as a central hub for the surrounding landscape, which is heavily shaped by the boundaries of the Siskiyou National Forest. To the southeast, the historic area of Takilma is situated near French Flat and the East Fork Illinois River, suggesting a legacy of settlement near the river forks.
