About this map

Coastal dunes and agricultural valleys characterize this late-1970s landscape, where the Southern Pacific railroad corridor links the developing communities of Grover City and Oceano. The map reveals a complex hydrographic system between the shoreline and the Nipomo Mesa, featuring a string of smaller water bodies such as Oso Flaco Lake, Celery Lake, and Black Lake. These lakes are caught in the shifting sands of the extensive Sand Dunes that dominate the western edge of the quadrangle.

Industrial development is evident near Callender, with an Oil Refinery, Coke Ovens, and a Conveyor Belt system positioned along the rail line. To the north, the township of Arroyo Grande Creek provides a fertile backdrop for the local economy, while the presence of Union H S and City Hall marks the civic center of the growing population. The eastern hills rise toward El Picacho, offering a sharp contrast to the flat Guadalupe Santa Maria Valley to the south.
