Mad River dominates the coastal geography of this Humboldt County region, winding through the alluvial plains of the Arcata Bottoms before meeting the Pacific Ocean. The landscape is a complex network of waterways, featuring Mud Slough, Liscom Slough, and Jackson Slough protected by a series of levees. These hydraulic engineering features reflect the era's focus on reclaiming and protecting low-lying coastal land for agricultural or industrial use.
