1948 Map of San Marcos

About this map

San Marcos Mountains and the Merriam Mountains dominate the northern landscape of this San Diego County quadrangle just after the war. The low-lying valleys are defined by the Atchison Topeka and Santa Fe railroad, which links the growing citrus and agricultural centers of Vista and San Marcos. Aviation history is prominent on this sheet, featuring the San Marcos Valley Airport and McCormick Airfield situated along Grand Ave. Education and community infrastructure are well-documented, from Palomar Junior College and High School to rural institutions like Richland Sch and Rich-mar Sch. The terrain is etched with numerous watercourses such as Agua Hedionda Creek and San Marcos Creek, while old property boundaries and local thoroughfares like Buena Road and Twin Oaks Road provide a clear view of the area's mid-century development.
