What happens when they want to erase!!???!?!?!

I saw a TV show that explained how the rocks do this. Anybody remember it? I can't recall the details.

Earthquakes.

Personally, I'm still looking for someone who's an Etch A Sketch candidate.

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.

The rocks are ordinary dolomite that tumbled out from the surrounding mountains.

I'm over 40% Dolomite!

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.

Meh; you should see what they do to our politics.

Mud and wind as I recall.

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

I think it was something to do with the rocks changing how things erode. Minute differences on the mud moves the rock ever so slightly each day with temperature changes. Over a year, you get mere inches, but it moves.

Did they check the other end of the trail?

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.

yeah it was called whachamacallit with whatshisface in it...he did the whateverit'scalled...

i would have googled it before i posted it but like you i am far too lazy...like you, my impulse to post nonsense overrides my common sense...

anyone else know what that stuff from that place from that show where they do stuff is called?

This is not a repeat from 500 AD

Of course not. Everyone else has been too stupid to do that.

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..

Came here for Dolomite...

/ off for a bowl of rat soup

Not a shred of moss on any of them. What do you know.

They were pushed.

I was there back in October. Love Death Valley :)





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

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.

Things that make you go hmmmm

I'm tempted to go out there with a backpack sprayer full of water and a stick to push rocks around so I can spell obscenities.

Yes, I was in that one.

Not just floods moving them all at once?

not a 25 pound rock pal.

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...

That Guy...From That Show!: Haliburton Cummings: anyone else know what that stuff from that place from that show where they do stuff is called?

Yes, I was in that one.

totally! you were the dude with that stuff and then you said such and such to what's her face...that was my favorite..uhm...what do they call segments of a series again?

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

Ice, ice baby.

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.

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

Ice, ice baby.

david_gaithersburg: Ripley's Believe it or Not?

Yup, it's ice, wind, and/or rain that creates a slick, frictionless surface for the stones to move. That's the prevailing theory. When you have no resistance, size and weight of the stone doesn't matter.

Man, look at the surface pattern of the desert from the already posted photos and come back.

And look into the climate of that particular place and then come back again.


'Very liitle water'!! Yeah, like because it's called Death Valley there'a a lot of death, right?!

I was there Death Valley at the end of March just before Drew's convention in Las Vegas.But I've never made it to the racetrack ... too chicken to face that road. But I did climb to the top of. Wildrose Peak.

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

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."

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 drove from Ohio to Santa Barbara, CA for a wedding, then went into Death Valley and camped for a few days before heading to Bonneville, UT then back to Ohio. I drove Racetrack Valley Road...in a Toyota Corolla. Took 2.5 hours each way, but it is worth it. Lost one hubcap on the way out, but found it on the way back :)

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.

Like how a glass will slide on a wet bar surface without prodding.

It is the earth revolving under the rocks. Geez, thought everybody knew that.

Solved, that was easy, next question.
