MORE ON THE INNER CIRCLE

Men coming and going from their duty stations at the Inner Circle approached by dirt road that wound around below the crest of the slope. This road then became a trench leading up the hill where concrete tunnels lined with steps led to each command post. This way, movement on Point Bonita could not be detected from the sea. This was probably the location described in a 1943 National Geographic article about wartime San Francisco.

This signal station, manned by sailors and coast guardsmen, kept the Navy informed of maritime traffic at the Golden Gate. If required, flags and blinkers could visually signal passing ships.
