Siuslaw National Forest encompasses this deeply dissected landscape, where the headwaters of several significant drainage systems converge at the border of Yamhill Co and Tillamook Co. High points such as Mt Hebo and the curiously named Burnt Ridge overlook a complex network of forest development roads and stream valleys, including the descent of Niagara Cr and Agency Cr. The terrain is punctuated by small mountain waters like North Lake and South Lake, while the curiosity of Asinine Bridge stands as a notable human-named landmark over Agency Cr. Further south, the map traces the intricate paths of Three Rivers and the W Fork Agency Cr, illustrating the dense hydrological web that defines this portion of the Northern Oregon Coast Range. This survey provides a precise record of the road network used for forest management, such as the SW Little Hebo Rd and SW Yoncalla Creek Rd.
