The timber and river country of Humboldt County is documented in this 2021 study, highlighting the intersection of industrial transport and complex topography. The Mad River and its North Fork carve through the landscape, defining the character of small settlements like Korbel and Riverside at the northern edge. Significant terrain features such as Fickle Hill and the deep Sullivan Gulch dictate the layout of winding roads like Maple Creek Rd and the Pacific Lambert Company Road.
