1981 Map of Anza

About this map

Anza serves as the focal point of this high-desert landscape in the early 1980s, where the convergence of Cahuilla Valley, Durasno Valley, and Terwilliger Valley meets the rising slopes of Thomas Mountain. The map reveals a complex mosaic of land use, with the San Bernardino National Forest bordering the Ramona Indian Reservation and Cahuilla Indian Reservation. This intersection of forest service land and tribal territories is marked by a network of seasonal water sources such as Hog Lake and numerous wells and springs that sustain the local ranching and residential sites. Notable local infrastructure includes the Hamilton Sch and several recreation sites like the Tool Box Spring Campground, reflecting the area's role as a gateway between the San Jacinto mountains and the desert floor. The distribution of small settlements like Costo and various trailer parks suggests a community shaped by its topography and the paths of Cahuilla Creek and Bautista Canyon.
