About this map

The City of San Bernardino meets the rising slopes of the San Bernardino Mountains in this pre-war survey. This map highlights the critical intersection of Southern California transportation and hydrology before the post-war suburban explosion. Three major rail lines—the Union Pacific, Atchison Topeka and Santa Fe, and the Pacific Electric—converge here, reflecting the era's heavy reliance on rail for commerce and travel.

Settlement patterns follow the mountain front, from Verdemont and Ono in the west to Del Rosa in the east. Local aviation history is preserved at the Shandin Hills Airport, while the Shandin Hills and Little Mtn (Lookout) provide natural elevation markers. The drainage of Devil Canyon and Lytle Creek Wash emphasizes the seasonal water systems that shaped the development of northern San Bernardino and the adjacent San Bernardino National Forest.
