Cucamonga Peak towers over the alluvial fans of the San Bernardino Valley, marking a sharp transition between the high wilderness of the San Bernardino National Forest and the structured agricultural and residential grid below. The mid-1960s landscape shows the transition from citrus-era settlements like Alta Loma and Etiwanda toward modern suburbanization, even as heavy rail lines like the Atchison Topeka and Santa Fe and Southern Pacific define the southern corridors.
