1901 Map of San Jacinto

Water management is central to the area's identity, evidenced by the Hemet Reservoir and various creek systems feeding the San Jacinto River. Away from the rail lines, the terrain transitions into the high peaks of the San Jacinto Mountains, where landmarks like San Jacinto Pk. and Tahquitz Valley tower over early resort locations such as Relief Hot Springs and Palm Springs. This record is particularly valuable for tracing early property lines and ranch names, such as the Potrero San Jacinto Nuevo and the historic San Jacinto Viejo.
