Decades-Old Mystery Put To Rest: Why Are There X's In The Desert?

Pez Owen was flying over the desert in her single-engine Cessna airplane when she spotted a huge "X" etched in the desert below. She says it was the strangest thing.
"It's not on the [flight] chart," Owen says. "There just wasn't any indication of this huge cross."
Then she spotted another one.
. . . .
We walk toward the base of a small mountain range, and that's when we see it: four 25-foot slabs of concrete inlaid in the desert floor that form a giant "X."
Penson kneels down to brush off the sand covering a tarnished brass plate at the very center. The engraving reads: "$250 fine or imprisonment for disturbing this marker — Corps of Engineers - U.S. Army."
That's who Penson and Owen contacted to get their answer.
These X's were once part of a top-secret government program called CORONA — the nation's first reconnaissance satellite program.
