2021 Map of Farallon Islands OE E

About this map

Pacific Ocean waters dominate this 2021 quadrangle, marking the maritime approach to the Golden Gate. The map delineates the administrative boundary for San Francisco, extending the city's jurisdiction far into the open sea. While many coastal sheets focus on terrain and infrastructure, this specific offshore survey is defined by its emptiness, providing an essential spatial record of the marine environment and boundary lines west of the mainland. It serves as a modern cartographic benchmark for the waters surrounding the Farallon Islands, where the deep ocean floor and protected marine zones meet the legal limits of California's most famous peninsula city.
