March Air Force Base and its expansive airfield dominate the southeastern landscape of this mid-century survey, flanked by the growing residential communities of Edgemont and Arnold Heights. The map provides a detailed look at the Inland Empire's post-war expansion, showing the urban footprint of Riverside pushing eastward toward the Box Springs Mountains. Educational and research institutions are prominent, including the University of California Riverside and its associated Experiment Station. Transportation infrastructure is a primary theme, with the Riverside Freeway and Escondido Freeway intersecting near the mountains, alongside legacy rail lines like the Atchison Topeka and Santa Fe and the Pacific Electric. From the citrus-growing history implied by the experiment station to the suburban developments at Sunnymead, the map documents a region in rapid transition.
