I thought that Mythbusters figured this one out a few years ago...

Doesn't explain how the Tupperware gets under the rocks, though

I thought the Stones had their own plane, you know...with the tongue logo?

I had to read twice to notice that the rocks are not actually in Death Valley, but only in Death Valley National Park. At elevation over 3,700 feet the racetrack can freeze much more easily than the valley floor.

Here's how one man finally solved the mystery.
no one has actually seen it happen
remains the most likely explaination


so the mystery is solved! Probably.

The article makes no sense unless you know that the "dried lake" is actually wet in the winter.

Yes, Dolomite. The tough black mineral that won't cop out when there's heat all about.

if only we had some way to record images.

If I'm reading that right, in order to move, the stones have to be encased in ice, and become semi-bouyant in standing water. If that's the case, why aren't the tracks immediately erased by the water turning the soil into liquefied mud?

SuperT: if only we had some way to record images.


IIRC, I think disturbing the soil or doing any kind of drilling or hammering into the ground is prohibited there, which makes it difficult to mount time-lapse cameras. I may be completely wrong about that.

I attended a lecture on the subject back in 2001. Mud flats & wind, nothing more is needed.

You are correct, the Parks department will not allow anyone to monitor the area with cameras or attach gps units to the stones or put up wind monitors.

And why arent the tracks turned into cracked mud like the area surrounding it once the temp reaches 179 degrees the other 300 days of the year.


After my lakes freeze over and the thaw comes its usually the ice that is touching something else that melts first.....like rocks and shoreline and my stakes for eel traps...the footings for my deck, dock and whatnot

After Googling and reading about Racetrack Playa a bit, I think the icy rocks are sliding across a thin layer of mud.

Sweet, my post got edited and/or there is a new filter running amok.

Wasn't talking about the Fark headline - I come to Fark for the my favorite website headlines.

Science advances by seeking more elegant solutions supported by more evidence.  That's just what science does.

I just have to accept the fact that my theory of "Playa Tectonics: How 'sailing stones' remain stationary and the playa moves under them" has been refuted by a wanker with a few rocks in a Tupperware bowl.

F*cker.

New filter. It replaces "С *l*i*c*k*b*a*i*t" with "my favorite website". I've noticed a couple others I haven't quite figured out yet.

OMG!

Its the same Hexagonal pattern that is on Jupiters pole

Something wonderful is going to happen....I just know it!

The answer: Wanna-be Ansel Adamses who think they are gonna get a job at Nat Geo who go out there and stage the rocks as they see fit to best get what they think is the ultimate photo

FTFA: These 'sailing stones', as they've been nicknamed, are so common on the the Racetrack Playa, they make it look like a well-worn racetrack, hence the name. (Playa is another word for 'dried lake'. Barricaded Gunman)

More like 93 years, since this 2007 article has actual video explaining the phenomena.

Also, I'm positive we've done this earlier this year. meh.
 
2014-07-27 10:54:26 PM
Only with peyote can one see the rocks set sails.

"Lorenz's research remains the most likely explaination for the sailing stones of Death Valley. "

Science Alert needs a spelling lesson.

Occam's Razor just shaved my coin purse
 
2014-07-28 02:00:17 AM
This is the same explanation as I have seen in every article on the subject in the last several years. The mystery has been solved for a long time.
 
2014-07-28 04:48:18 AM
These rocks go against the concept that rocks don't float.  The thing is they will float on anything that is less dense.  It also against the concept that the ground is solid.  Too bad that isn't true either, like all the false stories about glass being a liquid, the most of surface of the world happens to be a very slow moving fluid solution and those bits that aren't, just happen to be floating on something else that is.

DON.MAC: These rocks go against the concept that rocks don't float.


Very small rocks float.  Along with bread, apples, cider, gravy, cherries, mud, churches, lead, and ducks.
 
2014-07-28 12:55:16 PM
So, the rock is encased in ice and the bottom of it is dragging under water? How big of a slab of ice surrounding a 5 - 7 pound rock would you need to float this rock 250 meters?
 
2014-07-28 01:36:28 PM
Didn't we already know this? I feel like we already knew this. I'm sure I read something with almost this exact same explanation ages ago.
