About this map

San Jose Hills (Dalton Et Al) and the Puente Hills define the complex topography of this San Gabriel Valley corridor during a period of rapid suburban and institutional growth. The map illustrates a dense concentration of specialized facilities, from the sprawling Pacific State Hospital and Masonic Home For Children to the Naval Industrial Reserve Ordnance Plant. Educational expansion is evident at California State Polytechnic University (Kellogg) and Mt San Antonio Jr College. A massive transit and logistics network underpins the area, featuring the Atchison Topeka and Santa Fe Railway and the San Bernardino Freeway. Recreational and cultural landmarks like Puddingstone Reservoir within the Frank G Bonelli Regional County Park and the nearby Los Angeles County Fairgrounds mark the landscape as a regional hub of activity.
