Found this online. Apparently they figured it out after watching the most boring sport ever.

Haliburton Cummings: death valley is called death valley for a reason...it's dry....and hot...and has very little water...

go look up some info on death valley and come back...


Would this be a bad time to point out that the Racetrack is not in Death Valley?

It's in "Death Valley National Park". It is not in the valley named "Death Valley". More specifically it is located at an elevation 4000 feet higher and a hell of a lot cooler.

Some of the tracks involving multiple rocks follow paths that clearly are rocks locked and linked in ice, being blown in "tandem". Next mystery, please.

Invisible Pedestrian: "Trails as long as 1,500 feet have been found. What's even more puzzling is sometimes you can follow these trails and there's no rock at the end of it."

Did they check the other end of the trail?


DUH, no. The reason there was no rock at the start or end of the trail was that SOME MISCREANT EARTHLING STOLE IT. That's the one thing that is not mysterious.

I hate Chevy: Skeptoid.com covers this Link


Apparently a lot of people missed this link. Their explanation sounds pretty plausible.

Some amount of water covers the usually dry lake bed. Ice sheets form and either wind or currents push them into the rocks, sliding them across the bottom. Clay is pretty dense so it would deform from the weight of the rock, and it would take a while to fill back in. It's also pretty slick when it's wet. The water level during the event would determine which rocks move, since smaller rocks would be below the ice and larger ones too heavy to move. That would explain why some have trails and some don't.

GungFu: Haliburton Cummings: Peki: roughridersfan: I saw a TV show that explained how the rocks do this. Anybody remember it? I can't recall the details.

I dunno the show, but the details:

Basically, the sand turns into a slick surface when wet, and the canyon causes a wind tunnel. Nearly frictionless surface + wind + rocks = funky trails that mystify everyone.

nope. wrong.

i've been there and that surface is anything but "friction-less".

some of those rocks weigh as much as 20 pounds..so not wind..

the prevalent accepted theory is:
it happens as the result of ice crystals that form on them overnight melting in the daytime heat.

if you look, there's a youtube time lapse of these (maybe vimeo)

this happens in parts of Australia and Tunisia as well..


Hmmm. I've seen the videos before and I'd go for the wind and rain theory.

Ever placed a pint of beer/cup/ pot lid on a slighty wet surface and see it move on its own? Same kinda deal. The unlevel surface will allow for movement and the wind in Death Valley will do the same.


not a 25 pound rock pal.

And if you want youtube silliness, I'm making fun of Bear Grylls here, and being a dork here with the moving rocks.

There's been a few over the years but the one I remember was from the 80s and called, 'Arthur C. Clarke's Mysterious World'.

So, old shiat is old.


I think "Unsolved Mysteries" did one, and either it got redone on Discovery channel or that pathetic stew on History Channel. It's very frustrating because the conditions have to be so perfect, nobody can catch it on video, and there's no good way to fake it, either.
