Summit Valley serves as a key geographical intersection on this 1956 survey, where the West Fork Mojave River begins its course through the high desert landscape. The presence of Las Flores Ranch and the Las Flores School indicates a persistent ranching community established well before the modern water infrastructure shaped the region. To the north, the industrial footprint of the Santa Fe and Atchison Topeka railroad tracks follows the edge of Antelope Valley, marking the vital transit corridor through the Cajon Pass vicinity.
