About this map

The South Fork Trinity River carves a winding path through the borderlands of Humboldt and Trinity counties, where the canyon walls rise steeply to landmarks like Hennessy Peak and Gainor Peak. This 1970s landscape is defined by the meeting of the Six Rivers and Trinity National Forests, showing a remote interior before modern development intensified.

Settlement is sparse, concentrated at Hawkins Bar in the northeast corner and the isolated Cedar Grove Ranch along the riverbank. The map traces a network of high-elevation paths and ridges, including the McDonald Trail and the prominent Hogback Ridge. Numerous small water bodies and drainage systems, such as Sucker Lake, Big Lake, and Surprise Creek, illustrate the complex hydrology of this high country. These features provide essential data for those studying the 20th-century land use and topography of this river-centered wilderness.
