Siuslaw National Forest covers much of the northwestern terrain in this Benton County landscape, where the ridges of Franklin Ridge and Decker Ridge rise above a dense network of mountain drainages. The area is defined by its dramatic elevation changes, peaking at Flat Mountain and Buck Peak, with the deep incision of Hells Canyon to the east. Settled activity is concentrated along the lower creek valleys and peripheral roads, notably near the northern and eastern borders. Genealogists may find interest in the Emerick Cem located near Airport Rd and the Powell Cem situated along the slopes above Powell Cr. The map details a complex web of forest and access roads, such as Wells Creek Rd and Decker RD, which follow the contours of the land established by Greasy Cr, Spencer Cr, and Mercer Cr.
