1901 Map of San Luis Rey

About this map

The Santa Margarita River and San Luis Rey River define the coastal and inland landscape of northern San Diego County in this late-19th-century survey. Major coastal settlements including Oceanside and Carlsbad are shown alongside the critical Surf Line and California Southern Railroad routes, which facilitated the region's agricultural growth. Inland, the map captures the transition from ranch lands and early agricultural hubs like Fallbrook and Escondido to the rugged terrain of the Santa Margarita Mountains and Cleveland National Forest.
