1979 Map of Korbel

About this map

The Mad River dominates this landscape as it flows through the timber and ranch lands of Humboldt County in the late 1970s. The settlement of Korbel serves as a focal point near the confluence with the North Fork Mad River, while industrial activity is noted at the Mad River Fish Hatchery and several gravel pits and quarries along the water. The map documents a distinct pattern of high-altitude clearings, or prairies, such as Boynton Prairie, Garner Prairie, and Diamond Prairie, which break up the forested slopes of Fickle Hill and Boundary Hill.
