The Pacific Ocean dominates this offshore survey, capturing a remote section of the Farallon Islands within the maritime jurisdiction of San Francisco County. This specific area focuses on the northernmost reaches of the archipelago, primarily documenting the rocky outcrops of North Farallon and the Island of Saint James. The map illustrates the boundary line that separates these isolated geologic features from the open sea, marking the edge of the California state line as it cuts through the water. Given the limited terrestrial area, the sheet serves as a specialized study of these protected islets, which are significant for their unique ecosystem and navigational importance to mariners approaching the San Francisco Bay.
