Awesome. Thanks for posting this.

 

Here's a teaser of what lies behind the link:

 

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.

 

"There had to be some reason," she says. "So, of course, I immediately thought I had to get Chuck in on this."

 

Chuck Penson is her former colleague from the University of Arizona. Penson worked in facilities, and Owen worked in the planetarium. Now, they're adventure-seeking friends. That's how Scott Craven from The Arizona Republic described them in a recent article.

 

Their version of hanging out is exploring abandoned mineral mines and military radar bases. Mysterious X's plotted in the desert was too good to pass up.

 

"I was not going to rest until I knew what was going on with these," Penson says.

 

"It's conspiracy theory stuff, you know?" Owen says. "It's right out of the movies."

A giant grid of X's

Owen rolls out a map she received from the Defense Mapping Agency. It shows Casa Grande, Ariz. — the same area she flew over. Owen points to rows of little boxes that are drawn in.

 

"You can see each of these [boxes] is one of the crosses," she says.

 

"There's a grid of these things," Penson says. "There's not just a few, there's a bunch of these."

 

He counts 273 X's on this map. Each marker is spaced about a mile apart. Pez Owen had flown her little plane over the edge of a massive 289-square-mile grid.

Some do have PID's - GSAK Arizona sorts out 274 DMA's in 1966-67. kayakbird

We found it in 2004, very interesting and was some history to go along with those giant concrete arrows that are airway beacons. You can pull up those threads with just typing concrete arrows in the search....
