1901 Map of San Luis Rey

About this map

The coastal canyons and inland valleys of San Diego County are defined here by a series of significant ranchos and river systems during the final decade of the nineteenth century. The Santa Margarita y Las Flores land grant dominates the northwestern coastal area, where the California Southern RR and the Surf Line trace the Pacific shore through Oceanside and Carlsbad. This era captures the region before extensive modern development, highlighting the early agricultural importance of the San Luis Rey River and Santa Margarita River basins.
