The San Andreas Rift Zone marks the southwestern corner of this coastal Sonoma County landscape, where the South Fork Gualala River follows the structural lines of the fault. Further inland, the settlement of Annapolis serves as a focal point near Horicon Sch and the Beatty Ridge, while the Stewarts Point Rancheria occupies the terrain overlooking the river forks. This 1970s survey captures a transition in land use, showing a network of logging roads and ridges such as Grasshopper Ridge and School Ridge punctuated by fire infrastructure like the Mendosoma Forest Fire Sta.
