Better to let people keep entertained and hype up the nonsensical conjectures and "Mystery" than explain the more plausible reason it got there. Some guys put it there, somehow, probably without any crane, and broke rock. Must have been 4 strong men and their Jeep.
The reason why? Because when you've got curious people, they start coming like Pokemon Go players, scouring the landscape. Then whoopsies, the terrain blows out a tire in the middle of nowhere, they weren't prepared with food, and then first responders have to waste resources saving them and then coming back to retrieve their vehicles.
Just a remind of how the media informs buts makes sure to NOT EDUCATE.
