2017 Map of Hellion Rapids

About this map

The Alsea River cuts a deep, winding course through the southern portion of this landscape, creating the dramatic Hellion Canyon and the Hellion Rapids themselves. This territory is largely defined by the complex drainage systems of the Siuslaw National Forest, where high ridges like Peavine Ridge and Hellion Ridge separate numerous tributaries. Historically significant labels like Schoolhouse Cr point to early local infrastructure, while topographical curiosities such as the Surveyors Benches and the Upper Drift Creek Slide reflect the geological instability and surveying history of the Oregon Coast Range. The map details a dense network of forest development roads, including Nat For Dev Rd 1000 and Nat For Dev Rd 52, which provide access to remote features like Klickitat Spring and Ayers Lake.
