Between 1934 and 1936, a new Palo Alto Airport was built at the airport's current location. In 1989 a comprehensive area history analysis was conducted by Earth Metrics, based upon review of extant aerial photographs. The photo reconnaissance flights were flown in 1956, 1960, 1973, 1974 and 1980 by the U.S. Department of the Interior, and are archived by the U.S. Geological Survey in Menlo Park, California.
