About this map

San Bernardino National Forest dominates the northern reaches of this mid-1930s landscape, where the rugged terrain meets the expanding agricultural and infrastructure networks of the valley below. The Atchison Topeka and Santa Fe RR and US Highway Nos 66 and 395 serve as critical arteries through the pass, flanking the settlement of Devore. Evidence of early aviation and utility development is prominent, including the Fontana Intermediate Landing Field, an Airway Beacon, and the Fontana Power Plant.

A sophisticated water management system is visible through a series of structures including Weir No 1 through Weir No 4 along Lytle Creek, which feed into the broader Lytle Creek Wash. The map also captures local landmarks like the Glenn Helen Base Infirmary and Cajon Sch, alongside a transition to a grid of street names including Sierra Ave and Highland Avenue that hint at the suburban development to follow.
