1953 Map of San Jacinto

About this map

The Soboba Indian Reservation anchors the eastern edge of this mid-century landscape, where the San Jacinto River valley meets the rising slopes of the San Jacinto Mountains. Large-scale water infrastructure defines the region's development, evidenced by the Colorado River Aqueduct and San Diego Aqueduct cutting across the valley floor near the San Jacinto Reservoir. The settlement pattern centers on the grid of San Jacinto and the northern edge of Hemet, connected by the Atchison Topeka and Santa Fe railroad line. Local history is deeply tied to the thermal features of the area, specifically Gilman Hot Springs and Soboba Hot Springs, which served as regional destinations. Between the mountain canyons like Massacre Canyon and Castile Canyon, the map traces the early suburban expansion of Valle Vista and landmarks such as Park Hill and the Union High Sch.
