About this map

The Camp Roberts Military Reservation dominates the landscape of this 1948 survey, illustrating the significant military footprint along the border of Monterey and San Luis Obispo counties during the post-war era. The Southern Pacific railroad follows the course of the Salinas River, connecting the town of San Miguel with nearby hubs like Nacimiento and McKay. This corridor reveals a complex infrastructure of early aviation and utility, noted by the Landing Field and Sewage Disposal sites near the riverbanks.

Agricultural and rural development is evidenced by the Vineyard Sch and various canyons such as Vineyard Canyon and Deer Canyon, which funnel seasonal waters like Big Sandy Creek into the valley. The map documents the specific locations of reservoirs, windmills, and tanks that supported the cattle ranching and viticulture that historically defined this part of the Central Coast before more intensive modern development altered the land use patterns.
