2020 Map of Fanno Ridge

About this map

Black Rock sits at the northern edge of this high-elevation terrain in Polk County, serving as a focal point for a landscape defined by significant timber and watershed geography. The headwaters of the Luckiamute River and the Little Luckiamute River carve deep drainages through the central and northern sections, while the S Fork Siletz River cuts across the western interior. These waterways are separated by prominent landforms such as Fanno Ridge and Cougar Ridge, which dictate the winding paths of access routes like Valsetz Rd and Black Rock Rd.
