Have you heard of the sliding rocks of Racetrack Playa?
Racetrack Playa is a desert-looking place (apparently, a dry lake bed) that is littered with rocks.
The mystery is that these rocks move across the playa… seemingly on their own.
There are theories that the rocks move from wind, or ice, or animals. Go to the Wikipedia or geology.com articles for more information. (Wikipedia’s article is titled a more poetic “sailing stones”.)
I find the story fascinating: boulders moving across a dry, deserted lake bed seemingly on their own. And no one knows how it happens. The first part of the story makes it interesting. The second, that it’s unexplained, makes it really interesting.
My guess is that it’s the wind, maybe a combination of wind and ice, that makes the boulders move.
But I really don’t want people to figure it out for sure. I like that it’s unknown, because it allows for uncertainty and possibility.
Here’s to mysterious, sailing rocks!
