The Mad River winds through this coastal timber and agricultural landscape, defining the geography between Korbel and the Butler Valley. This 2015 survey shows the area's industrial character through the Simpson Nursery and a Quarry, alongside a network of access roads like Fickle Hill Rd and Maple Creek Rd. The terrain is marked by significant elevations such as Fickle Hill and isolated pockets of flat land like Camp Four Flat. Along the northern edge, the settlement of Riverside sits near the confluence of Hatchery Cr, where the Old Fish Hatchery is noted. In the south, Kneeland serves as a remote anchor point for the rural road network, while smaller landmarks like Lost Meadow and Sullivan Gulch offer specific points of interest for those studying the local topography of Humboldt County.
