San Bernardino Mts and the San Gabriel Mountains converge at the critical transport corridor of Lower Cajon Canyon. This survey captures the mid-century infrastructure of the pass, where the Atchison Topeka and Santa Fe and Union Pacific railroads run parallel to the Barstow Freeway. The transition from the steep, canyon-cut San Bernardino National Forest to the alluvial plains of the Muscupiabe land grant is clearly defined, showing the shift from mountain ranching at Glenn Helen Ranch and Hitching Ranch to the early suburban grid developing around Devore. Local landmarks such as the Cajon School and the Fire Control Station anchor the community, while the southern portion of the sheet reveals the aviation history of the region through Gilfillan Airport and Miro-Fontana Airport.
