1981 Map of Anza

About this map

The high mountain valleys of southern Riverside County are defined here by a series of distinct basins, including Anza Valley, Cahuilla Valley, and Terwilliger Valley. This 1980s landscape shows the intersection of the San Bernardino National Forest with sovereign tribal lands, specifically the Cahuilla Indian Reservation and Ramona Indian Reservation. The settlement patterns revolve around the communities of Anza and Hamilton, where a network of rural routes like Bautista Road and Contreras Road connect scattered wells and small clusters of development. Evidence of local recreation and transportation infrastructure is present in the numerous campgrounds, such as Tool Box Spring Campground, and a localized Landing Strip. The presence of a small Cem near Cahuilla provides a focal point for genealogical interest, while the rugged terrain of Thomas Mountain looms over the valley floors.
