About this map

San Bernardino National Forest dominates the upper landscape of this 1960s study, where the steep terrain of Penstock Ridge and Ruddell Hill meets the alluvial fans of the Lytle Creek Wash. The map documents a critical transportation corridor through the Lower Cajon Canyon, showing the complex intersection of the Southern Pacific, Union Pacific, and Atchison Topeka and Santa Fe railroads alongside the Barstow Freeway.

Settlement patterns transition from the isolated outposts of Scotland and Devore Heights to the emerging suburban grids of Rialto. Notable local infrastructure includes the Gilfillan Airport and Rialto Municipal Airport (Miro Field), as well as the Glen Helen Rehabilitation Facility. This era captured by the State of California Department of Water Resources and USGS shows the region's managed water systems, from the Lytle Creek Ranger Station to the numerous gauging stations and powerhouses along the canyons.
