Scattered in a 16-mile square grid in the southern part of Casa Grande lies a collection of more than 250 concrete markers, resembling a Maltese cross, that were installed in the ground the Cold War 1960s. Although they were in plain sight, their purpose was not publicly disclosed as they were part of a top secret reconnaissance program run by a government agency whose very existence was not revealed until 1992. The whole story of this program reveals that the U.S. was committed to developing the technology necessary to learn everything about the location of ballistic missile launch sites, nuclear submarines, and bombers capable of reaching us. Today we can just look at Google Earth.
