1975 Map of Corona North

USGS Topo · Published 1979

About this map

The Santa Ana River basin reveals a complex transition from high-density agricultural grids to expanding suburban footprints in the mid-1970s. This orthophotograph, derived from aerial imagery taken by the Department of the Interior and Geological Survey, captures the stark contrast between the orderly fields of the north and the winding residential streets and rugged topography of Riverside to the east. The floodplain surrounding Prado serves as a central geographic anchor, where the natural watercourse meets the engineered landscape. Researchers can observe the evolution of land use during a period of rapid development, as once-continuous orchard and crop rows begin to give way to commercial corridors and housing tracts, all framed by the distinctive drainage patterns and canyons that define the local terrain.
