About this map

Anza and the surrounding high valleys of Riverside County are meticulously documented in this 1981 survey, reflecting a landscape defined by ranching, water management, and federal land boundaries. The map illustrates a transition between the San Bernardino National Forest to the north and the expansive tribal lands of the Cahuilla Indian Reservation and Ramona Indian Reservation. Evidence of local infrastructure is clear through the presence of several landing strips and a network of mountain roads such as Thomas Mtn Road and Mitchell Road.

Water sources are vital in this arid terrain, highlighted by the drainage of Cahuilla Creek through the Anza Valley and the smaller Durasno Valley. Key community markers like the Hamilton Sch and a local Cem provide essential touchpoints for genealogical research. The varied topography, from the heights of Thomas Mountain to the depths of Bautista Canyon, dictates the settlement patterns and roadway alignments throughout the region.
