Dig into the secrets of the “Mount Tam Golf Balls”: http://bit.ly/MtTamGolfBalls
1950s-70s: For decades you could see them from across the bay — two giant white “golf balls” atop Mount Tamalpais. Many residents knew they had something to do with the military, but the secrecy that initially surrounded them created rumors that persisted long after they had served their purpose. So what exactly was perched on the west peak of Mount Tam, hiding in plain sight? A trip to The Chronicle’s archive produced images that shed light on the mystery. (1) The U.S. Air Force Radar Station as seen from the air in 1963. (2) Officers track aircraft at the base on Dec. 10, 1953. (3) Chronicle front-page coverage from Dec. 14, 1953. (4) Lt. Col. Wayne Mashburn, who led the radar station in the 1970s.
