About this map

The San Marcos Mountains and Merriam Mountains dominate this northern San Diego County landscape, shaping the development of the valleys below. In the late 1940s, the region transitioned from rural grazing lands and orchards toward more established educational and infrastructure hubs, evidenced by the presence of Palomar Junior College and High School and the San Marcos Valley Airport. Transportation is anchored by the Atchison Topeka and Santa Fe railroad, which skirts the southern foothills near San Marcos.
