The Geology Behind the "Sailing Stones" of Death Valley
Death Valley's Racetrack Playa is the best known and most famous of the various places where "sailing stones", or moving rocks, leave tracks behind them on dry lake beds. This phenomena has been documented for nearly 100 years at the Racetrack, but it was not conclusively described until 2014! Various other researchers had postulated on the true cause prior to that, but the 2014 paper showed exactly the conditions required for the rocks to move.
The sailing stones are moved by sheets of very thin ice which form atop a temporary lake which sometimes occupies the playa's south end, where most of the rocks are. High winds blow these sheets of ice around, often eddying and spinning around, which in turn drag and push the rocks across the muddy and slippery surface. There is less than 2 inches of vertical relief across the playa, so some of these rocks - which range up to hundreds of pounds - can move very long distances into the playa.

Devils Hole: Nevada's Window to the Aquifer
มุมมอง 20K3 หลายเดือนก่อน
Devils Hole is a spring-fed pool in southern Nevada, and also a cave of unknown depth. This mysterious hole has been the site of diving accidents, scientific research, and political controversy due to its population of Devils Hole Pupfish, a tiny fish who's entire habitat is confined to the uppermost shelf of this cave. Geologically, it's a fissure dissolved out of the limestone by groundwater ...

FINALLY! An Explanation! Thank You! 😊
@@e.d.2096 you’re welcome!
It's because they're haunted by evil spirits! Is what superstitious Magical Thinkers want you to believe.
There's no one better to have on a road trip than Andrew. He is a one-man roadside geology, gazing out and pointing to a geographical feature, he has interesting and poignant commentary, general and specific, scientific and historical, and he's a super talented musician with an ear for great sound, from the resonance of giant organ pipes to the haunting, enigmatic vibes (plus saxophone) of Vangelis's Blade runner. If you're lucky, he'll serenade you with his melodica by the campfire, where he helped ensure the campsite was safely selected outside of flashflood hazards 😅.
What time of year was this filmed?
This was filmed in late March.
This was solved almost 10 years ago by another youtuber.
Well, that TH-camr may have reported on the findings of the Norris and Ray paper from 2014, but the phenomena has been understood for the better part of 30 years at this point.
Ice and wind isn't it?
Indeed, as explained in my video!
Every time I've been out west I wished I had a geologist with me. Thank you. I was my favorite science req too but I took it so late I regret not taking more classes in it.
@@curiousnomadic I’m glad you find it interesting! There are some excellent roadside geology guides out there that really illuminate what you can see on the road.
@@BetterGeology I was so fascinated in just the Parowan Gap. The land seems so incredibly old out there and I can't help but ask how so much of it formed.
I was on the Skeptoid Podcast field trip when you explained the process. Your TH-cam expanation is wonderful, but it was amazing actually being THERE when you explained the process. Thanks.
@@tomwickland I’m glad you enjoyed the trip! That was a blast for me to help with.

Andrew, your rock solid outfit matches the splendor of the location. Love your concise “no shit” ice sheet explanation of the sailing rocks. 🪨on👏
@@DeathValleyDazed thank you!
Morro Bay local, we always called it 7 sisters though I think there are 11 total.
Hey Andrew, love the geology vids, great info! I found u thru your dad's site Skeptoid, which i think should be required reading for everyone. It's obvious you learned a lot and turned into a great guy like him. Thanks to you both for your endeavors to educate the populous in a fun way.
@@JeffHedrick-zo8db thank you very much!
good info
Well....that was less informative than my 6th grade text book.
@@n5sdm sure hope you don’t expect a textbook’s worth of information in 3 minutes 😆
The Devil has a lot of things... Devils hole, Devils mountain, Devils tower, Devils rock, devils cave, Devils Lake, Devils food cake, Devils stairs, Devils bridge, lil Devils strip club.... the list just goes on and on! must have a really good marketing team.
@@gsmith4295 Even within Death Valley there’s also Devils Golf Course and Devils Cornfield
Granted, this ice age lake maybe filled the valley at one time, but that does not explain the fish. It would have made more sense to say, the Biblical flood or another way that transported the fish, then the lake receded.
Nicely done, Andrew! We continue to be impressed with your videos. Thank you!
Thank you!
I've been scuba diving in there mid 60s. It's beautiful! We were looking for my friends who went diving there, but they were never found.
@@wormrose01 wait, you knew them? That’s incredible. An amazing and sad story.
Must be strange diving in such a narrow slot
That's too bad about your friends. When I was a kid, there was a story about a scuba diver in Walker Lake that went missing, and weeks later, he was found in Pyramid Lake, a little over 100 miles away. Then there's Earl Dorr. He discovered an underground river under Kokoweef Peak that had black sand beaches loaded with gold flakes and small nuggets. He also said the water level rose and fell with the tides. There's some strange stuff happening under that desert.
I’m going to guess that the fish eat flying insects that happen by.
@@Boris_Chang they eat the algae that grows at the surface of the pool, mostly. I suspect insects may play a role as well.
I want you to come to Montana and let me show you some places that I want answers to.
Thanks. ✌🏻👊🏼
You’re welcome!
You mean after the Waters of the deep receded during the time of Noah you know the flood. 😊
Sounds interesting! What was Noah, was it the indigenous name for a storm?
Although variable population mutation rates make it difficult to gauge, several recent genetic studies suggest that that the Devil's Hole pupfish only diverged in the last 1,000 years from the Amargosa Pupfish. My favorite theory is that they were originally brought to Devil's Hole by humans.
That’s interesting, now you’ve got me reading about that!
Devils hole is a jail. You cannot even see the fish. See the Pupfish at Ash Meadows and Shoshone instead.
Yes, the Crystal Spring boardwalk at the visitor center is a much better place to see fish. They have several other species as well.
@@BetterGeology I think Point of Rocks is even better. There is a spring fed pool there where you can get pretty close. Shoshone also has a small pond where you can get very close.
Neat!
@@loosefish9889 glad you liked it!
Los Vegas has been trying to steal the water from this area ,Pahrump is also sinking more well s as its population expands ,those fish are what keep them from stealing the water
Las Vegas doesn’t access water from this aquifer system, but Pahrump certainly does, as well as the whole Amargosa Valley and Beatty.
I heard about this years ago , I thought these guppies had disappeared and they don't know if they moved further underground or not .
@@josephmedina6403 Nope, the population is very stable right now and they recently counted the highest number in 30 years!
I didn't realize the effects distant earthquakes had on the water. Very interesting.
It’s possibly my favorite fact about this site
As usual, spot on.
Thank you!
I was watching another Science channel and they warned us "There is some Maths coming up" then told us there was 80% of one thing and 20% of an other one. OMG. It is nice to learn about stuff we may not be familiar with without having to suck our thumbs .glad I found you.

Do you believe or have proof that the Cascadia won't react or cause Yellowstone or San Andreas to go off.
The main reason we can say that with certainty is that this old event was simply too small. The Cascadia Subduction Zone operates on its own conditions because it is so large, and smaller earthquakes like this are on unrelated systems (usually). Yellowstone's major eruptions are completely independent of any earthquake systems because it is fueled by a hotspot which derives its magma from the Earth's core. When Yellowstone is ready to go, we'll know years in advance, partly because it will trigger lots of earthquakes beforehand!

i am scared of earthquakes but want to sit in middle of nature like u
Well, you can do both if you want!
AMong other things, Petroglyph Point tells the story of multiple eruptions of Mt. Shasta which can be seen in the distance.
Anybody ever seen the canyon carved by the Mt. St. Helens eruption?
Yes, it’s pretty dramatic. Amazing how quickly things can erode when they’re very soft and loose - it was as if the area was buried with sawdust.
Do you know anything about the coal / peet deposits on the cliffs between point wilson and north beach? They are closer to point wilson in an area that is impassable at high tide.
I don’t think I’ve seen those specifically, but there are a good number of similar deposits around North Beach. Hard to say exactly what the cause is, but I think some of it is due to uplift caused by rebound after the glacier melted. Some parts of the Salish Sea area are rising by nearly a centimeter per year even 15,000 years later!
Really enjoyed the breakdown of your research. Do you have a link to your research? Has it been published yet?
Thank you! I was really hoping it would be through peer review by the time this video was ready, but it’s still in review. I think it’s on a pre-print server somewhere, I’ll look.
Nope, not publicly available yet. I’ll make an announcement when it is published, so make sure and subscribe to the channel to be notified when it’s out!
