The map above shows the roads in the Gualala River basin as mapped by UC Davis ICE from 2000 aerial photo graphs. The highest road densities tend to be in the northern and western basins where industrial timber harvest is the primary land use. Road densities are lower in the eastern Gualala watershed because of unstable terrain associated with the Central Belt Franciscan Formation. Image from the KRIS Gualala Map Project.
