The Siuslaw National Forest encompasses a significant portion of this landscape at the intersection of Yamhill, Tillamook, Polk, and Lincoln Counties. The terrain is defined by the headwaters and drainages of several major regional waterways, including the S Yamhill River, the Salmon River, and the Little Nestucca River. Small settlements like Boyer and Midway sit along Hebo Rd, serving as focal points for the surrounding timberlands and ridges. The map illustrates a complex network of forest roads such as SW Agency Creek Rd and Sourgrass Rd that navigate the high points of Sourgrass Summit, Leno Hill, and Saddle Bag Mtn. To the southeast, Hidout Reservoir and the Rogue River further mark the drainage patterns of this heavily forested upland region.
