About this map

Blue Lake sits at the southwestern corner of this landscape, serving as a gateway to the mountainous terrain of Humboldt County. The settlement pattern here follows the drainage of the Mad River, which is fed by the North Fork and East Fork Mad River. Higher elevations are defined by long, narrow ridgelines like Tip Top Ridge and Wiregrass Ridge, which overlook a series of small meadows and flats such as Elk Prairie, Miller Prairie, and Round Prairie. These clearings provided essential open ground amidst the heavily dissected timberland.
