1965 Map of Oceano

About this map

Pismo Dunes and a complex system of coastal lakes dominate the shoreline of this mid-1960s survey, illustrating a unique landscape where agricultural land meets shifting sands. The drainage patterns of Arroyo Grande Creek and Oso Flaco Creek define the low-lying valleys, while the Nipomo Mesa provides a raised plateau for cultivation. Industrial activity is concentrated near Callender, where an oil refinery and coke ovens sit adjacent to the Southern Pacific tracks, reflecting the era's energy infrastructure.
