1975 Map of San Bernardino North

About this map

San Bernardino is seen here in a mid-1970s orthophotoquad, showing the dense grid of its northern neighborhoods as they met the steep ascent of the San Bernardino Mountains. This aerial perspective captures the complex interface between the urban sprawl and the towering ridge line that includes Arrowhead Peak. The map provides a high-resolution view of the industrial and residential transition into Rialto to the west and the mountain community of Crestline perched along the northern rim. The stark contrast between the structured city streets and the broad, braided expanse of Lytle Creek Wash illustrates the local management of alluvial fans and seasonal floodwaters. This imagery reveals the precise footprint of development before the continued expansion of the Inland Empire in the late twentieth century.
