About this map

China Camp sits at the southern edge of this coastal survey, where the hills meet the extensive mudflats of San Pablo Bay. The landscape is dominated by the shifting interface of water and land, characterized by the wide tidal channels of Petaluma Creek and Novato Cr. To the north, the Northwestern railroad line cuts through the marshy terrain near Black Point, navigating a complex network of levees and reclaimed lands like Tubbs Island.

A notable mid-century coastal presence is marked by the Military Reservation situated along the shoreline north of Gallinas Creek. The map documents a period before significant modern development, emphasizing the natural hydrology of the region from Midshipman Pt to the rocky outcrop of Rat Rock. The detailed charting of depth curves and pipelines reflects the area's importance for maritime navigation and regional infrastructure during the Earl Warren administration.
