1951 Map of Simi

USGS Topo · Published 1968

About this map

Simi Valley and the surrounding high ridges define the landscape of eastern Ventura County in the early 1950s. The settlement at Moorpark and the Virginia Colony cluster along the western edge, while the town of Simi anchors the central valley floor. This era is marked by a nascent transition from agricultural land use to early suburban development, though vast tracts remain dedicated to ranching and resource extraction. Significant oil wells and oil tanks are concentrated on the northern slopes of Oak Ridge, reflecting the industrial importance of the region's petroleum fields.
