1959 Map of Pico Creek

Coastal geography is defined by prominent natural features such as Piedra Blanca and Pico Rock, while the drainage of Pico Creek marks the transition from the hills to the shoreline. The inclusion of San Simeon Beach State Park reflects the preservation of the shoreline for public use, even as purple-ink revisions from the late 1970s indicate subtle shifts in the built environment and local water resources like Springs.
