1904 Map of Southern California Sheet No. 1

About this map

The Los Angeles basin and the surrounding mountain ranges appear at a transformative moment before the era of major freeway development. In this early twentieth-century landscape, the regional economy is defined by the Santa Ana River and San Gabriel River systems, which supported the burgeoning citrus belts around Riverside and San Bernardino. The map highlights the critical importance of water management in the arid West, featuring early infrastructure like the Bear Valley Reservoir and Hemet Reservoir. Coastal settlements such as Santa Monica, Redondo, and San Pedro are depicted as distinct port and resort towns, while the interior is dominated by expansive federal lands including the San Gabriel Timber Land Reserve and the San Jacinto Forest Reserve. Extensive rail networks, including the Southern Pacific RR and A.T. & S.F. RY., connect the coastal plains to the high desert, illustrating the transport corridors that dictated early Southern California growth.
