About this map

Cajon Pass serves as the focal point of this turn-of-the-century landscape, marking the critical transition between the southern mountains and the high desert. The Southern California Railway snakes through the pass, following the corridor from Summit toward the developing railroad town of Hesperia. This infrastructure represents the lifeline of early 20th-century San Bernardino County, connecting the coastal basins to the interior through this narrow gateway.

South of the pass, the terrain is dominated by the Angeles National Forest, where steep drainages like Lone Pine Canyon and Horsethief Canyon feed the nascent water systems. Sparse settlement is visible at family outposts such as Burcham Ranch and Applewhite Ranch, highlighting the isolated nature of ranching life before modern irrigation. To the north, the Mohave River and the sweeping Antelope Valley illustrate the vast, open character of the Mohave Desert at a time when water and rail were the only constants.
