What does a geologist say about the Carolina Bays?

Will the Carolina Bays mystery ever be solved?
The Carolina Bays of the Atlantic Coastal Plain have received lots of attention since LiDAR imagery made them more visible. They probably number in the 100's of thousands, and their origin is still the subject of much debate. After the LiDAR imagery was produced, impact origin theories became popular due to the consistent shape and alignment of the bays. Other characteristics of the bays are not consistent with an impact origin and strongly support a completely different history. This video shows what the bays look like in different places and compares them to modern-day features elsewhere on Earth. How do you think they formed?

I grew up in the Cape Fear River valley of North Carolina in the 1950s and played in the bay lakes as a child. Then in my teens, I obtained my first pilot's license and, as part of my training, I had to do cross-country flights across Bladen, Cumberland, Columbus, Robeson and nearby counties (many of these are North Carolina/South Carolina border counties). I was shocked and enthralled to see from the air what I had lived among. Of course, my instructor (a prototypical "old pilot" of crusty outward appearance covering a very intelligent and thoroughly experienced person inside) told me about the "impact theory" and the alignment of the ovality did seem to support that superficially but the features always appeared to me to be more superficial and less violent than an impact event would create. Decades later, following my "office job retirement", I took on a part-time job with the Forest Service as a pilot and was assigned patrol and fire-fighting assistance duties in southeastern NC and the bays were part of my everyday life. We'd use them as navigational landmarks and as descriptions of locations for communication with ground personnel. One of my favorite bay lakes is "Horseshoe Lake", it's approx 15 miles SE of Fayetteville, NC and marks approximately the northern border of Bladen county and the airspace restrictions around Fayetteville airport. I don't know exactly what it looks like from the ground but the "wet part" of the lake is the south-western edge periphery of the full bay, with a marsh extending across the nw/se axis of the bay and the typical berm edge arc across the northeastern portion of the bay. This northeastern segment cannot be seen from the ground but its extent and connection to the "wet lake" area is immediately and easily seen from the air. Another apparent feature is the variety of the features -- full oval lakes, to clear oval bays with a central "sump" of wet or moist ground, to dry fully formed bays, to vague bays with what might be described as blown-out edges, and the bays that have been obscured -- or not!! --- by agricultural land use. I found this video fascinating and full of excellently presented facts versus the usual soup of "theories" surrounding other depictions of the bays. Your scientific observations and analyses have greatly confirmed and explained features I've lived among and been very curious about for my entire life. For that, I applaud your work and personally appreciate it greatly.

Well, I’ve been thinking about this video for months. This is gonna sound crazy, but I guess I’m gonna break it down for y’all: what if the bays were formed originally as little ponds like in the example in this video of Alaska. These ponds would freeze over in the winter and partially melt in the summer, creating an ice disc on the surface of the ponds. Then the wind blows this ice disc to one side of the pond and scrapes the edges. As the wind changes direction, it pushes it to another side of the pond, also scraping it, acting like an erosive Spirograph. As the ice sheets retreated in the north, the weather got warmer and the ice discs stopped forming, stopping the erosive growth and locking the axis of the ellipse in the current position. Then the shallow ponds got filled in with sediment, leaving behind the only the deepest and largest of the ponds. Then the water dried up and the sand left behind is being blown by the wind and undercutting the bays next to one another.

[@gravitonthongs1363]

I think there is a video by SciShow that describes their formation like that. It was my preferred explanation for a while, but now I don’t think ice is required. Deflation hollows from water breaking down layers of clay avoids the claim that ice layers would not form so close to the coast at the most southern locations.

[@TheGeoModels]

A bunch of the Alaska lakes have an ice disc in them in the current google earth imagery

[@jameslafontaine5557]

This is good, but there is a reason all these ponds or lakes were there in the first place if true. Also, simply taking a sediment core will show varves and that would be definitive proof they were indeed ponds, regardless of how they formed. The pattern of these does remind me alot of lakes in the tundra, as well as bog and permafrost formations. All lakes are there for a reason, and its usually a pretty interesting one.

[@theeddorian]

This a an interesting analysis, and, if you are interested Pleistocene climate, serves to suggest that the climate might have been far harsher than we normally imagine. The large, partially eroded "bay" discussed around 11:00 shows multiple concentric lines of vegetation along the lower right. Those look like shore line features and might indicate the feature, which is only partially defined, might in reality be sequential meander margins of a stream migrating up and left in the image. With LiDAR it should be poissible to detect relict thermokarst landscapes even in heavily forested environments. The eastern seaboard and plains were heavily forested prior to European colonization. The Lena River example also includes meandering streams that are not incised.

[@testbenchdude]

I think I subbed to your channel after you posted this, so apologies that I'm 9 months late to the party, but it just popped up in my feed. Carolina Bays are one of my favorite morphological features. It's so easy to get caught up in the hype trying to tie these into "that impact theory", but I found that trying to find out their actual depositional environment was just way more fascinating. These things occurred over at least the last 125k years if we are to believe the results from various marine isotope studies. They give us a glimpse into the climate and weather patterns of that time, and that just really gets me going. Sure, comet impact ejecta and "a very bad day on Earth" is sexy and all, but the most likely explanation is way more interesting to me, and videos like this are exactly what we need to dispel the myths. (Also, it's pretty easy to find LiDAR of bays overlapping dunes overlapping bays and being cut by rivers. All of which simply could not have happened all at once.) I'm not inclined to agree with the thermokarst oriented lakes being related to the bays though. Similar in some respects, but I'm not sure I could be convinced that the periglacial environment extended as far south as Georgia. Also, to my eye, the majority of thermokarst lakes seem to exhibit a much higher degree of irregularity in their shapes than the bays. Can't disregard their shared aeolian features though. So, super similar, sure, but not exactly. Maybe the thermokarst lakes are what the bays looked like in their infancy, and then smoothed out over time? Maybe the thermokarst lakes will resemble the bays in tens of thousands of years... Another cool place to look at is coastal southern Argentina, btw. Again, I have no idea if this was periglacial, but there seem to be extant oriented lakes there as well. FWIW, Cintos used to have a lot more publicly availably LiDAR imagery for Google Earth; I have it all saved to one of my old laptops. I really need to back all that up; it's got every bay cataloged from the project. I have no idea why they don't seem to host it anymore. And as a personal aside, I fly a drone equipped with LiDAR at one of my worksites, located just north of the Delaware Bay in NJ. I know there are bays there but they have been so heavily obscured by industry and farming so it's very difficult to pick them out. I haven't detected any obvious bay features at my site, but if I ever do... well, I'll be sure to absolutely geek out over it. Anyway, sadly, you'll probably not be invited to the JRE any time soon... ;)

Quite a few playas and deflationary hollows called fairy circles in Australia which are similar looking geological formations. I agree that reality is far more fascinating than impact fantasy.

[@ChrisPBacon-yz6nk]

Randall Carlson has the best explanation for Carolina Bays. A meteor crashed into a glacier during the last ice age and threw huge chunks of ice into the air that fell back to Earth and made elliptical craters. Probably more than one meteor and hence different alignments. Edit: Now that I’ve finished your video, maybe yours is the best. Who knows.

[@TheGeoModels]

Well glad that you saw it through, either way! Lots of folks get fired up over this one!

[@danhnguyen-fn9eb]

@@TheGeoModels Actually Randall's explanation for some of the bays include multiple impacts over long periods of time and impacts that came in different trajectories and angles. While he has questioned whether it was comet or asteroid/meteorite I think that question was left in the air suggesting that both had happened over time. What you may not know(please excuse me if you do) is that Randall's discussion about the Bays was in relation to the larger discussion about the massive flooding in the Northwest at the end of the Pleistocene and just before the Younger Dryas and also the massive dump of floodwaters into the Pacific and Atlantic. The main part of the discussion was what could cause such a massive amount of Glacier melt water that did what it did when the Ice dams failed. Global warming at the time could account for some of it but not all of it. We're talking flood waters that raised the oceans by several hundreds of feet in a relatively short period of time. Plus, it happened a couple of times. It took a lot of thermal heat to melt so much ice that 1) kept the melt water liquid in an area known for mile high glaciers 2) carving bowls or pockets in the ice to contain the melt water. Since whatever happened on the Ice happened about the same time as the bays it's a reasonable assumption that the two phenomena are related. I believe Zamora covers all of this as well in a more scientific way than I ever could. I would find it hard to believe that the Ice would be spared an impact or comet Tunguska style with as much area of the planet that was covered in ice. We've all seen what happened at Tunguska over a forest. Now put that thermal energy over a large glacier.

[@gravitonthongs1363]

@@danhnguyen-fn9eb Carlson and Zamora both have magical explanations for most of the reasons geologists don’t support them, but they just don’t hold up to scientific scrutiny. Major flooding is expected with the melting of an ice sheet due to the temperature rise. There was no ejecta from Tunguska, but plenty of fragments and other evidence that can’t be found from the YD period.

Really neat analysis. I saw info about these bays before and was convinced it was from impacts and I just assumed different impacts caused the different orientations and ages. But I think you’re right. Sandy lakes with high winds.

[@DJJonPattrsn22]

As I recall, all of the versions of the impact theory I've learned of involve multiple primary impacts in quick succession, some simultaneous, that each generated their own secondary "splash" events that are proposed to have created the "bays". The ideas were of one or more objects that broke up before impact, possibly colliding shortly before impact, or perhaps even a swarm of smaller objects to begin with. Some have compared the event to the various annual meteor showers we experience on Earth as our orbit takes us through debris fields.

[@gravitonthongs1363]

To explain the ejecta distance you need the biggest impact in billions of years, lots of small impacts provides even less explanation for the ejecta distance.

[@thedunelady]

Aeolian scientist here: I'd suggest that the parabolic dunes you show at 10:00 (and again a few times) likely predate the bays. Why I think this: - The dunes are roughly the same size as those nearby (across the river, for example) that aren't connected to bays. Dunes of similar size like this tend to have formed in the same time frame, from the same wind patterns, with the same influx of sand. Of course dunes can be reactivated so this can get tricky. - The deep bay in the upper center seems to have degraded dune deposits to its west, which would be upwind rather than downwind. Although you could argue that those are derived from the next bay to the west (the one with a stream channel). - The deposits (lunettes maybe?) downwind of the bays tend to be on their SE side, suggesting a ~NW wind formed them. However the parabolic dunes were formed by a SW wind. To me this suggests that the bays and parabolic dunes were formed at different times when the strongest winds blew from different directions. (It could also be a seasonal thing: if the bays are related to ice like those in Alaska/Russia then they'd be shaped by winter winds, whereas the parabolic dunes could be shaped by summer winds when the landscape dries out enough to mobilize sand.) Either way, these things are very cool and a wonderful mystery. I just think that this particular location shows bays crosscutting dunes. The example you show at 11:30 clearly shows dunes crawling on top of a bay, so I agree that their history is intertwined. Thanks for the close look at these things!

[@massspectrometer6757]

I have so many thoughts about your idea of it being similar to the formations in the far north. If it were ice related, the thawing ice sheet on the lake/pond/bay could very easily move the sand. Not just once but many thousands of times. I recall the wandering stones in the deserts being explained in this way. The ice freezes around the stone and then drags the stone around as the ice sheet moves with the wind. My initial thought was these rings being formed by tussocks. A floating mound of organic that is blown around slowly digging up a depression below it as the roots run aground over large time scales.

[@ralphbagwell3732]

[@jollyroger7624]

None of the thermokarst lakes has the perfection of the bays, none have the overturned rims nor the perfectly flat bottom. I think if you were to do a serious investigation we would find unlike the bays the thermokarst lake's orientation conforms to the base strata.

[@Insidious_Rage]

I have a feeling they were created long ago when water more covered the area.

[@josephkern4081]

I'm no geologist but I got the impression it was something striking an ice sheet before you mentioned it and what made me consider it is the elliptical impressions like a lower velocity object tumbling (chunks of ice) striking and then melting into shallow ponds causing the sand and soil to settle evenly ( a large meteor exploding before impacting the ice sheet would explain all the diffrent impact trajectories (it is just my opinion )

[@DEK1206]

A very cool video. Thanks. Has anyone excavated a trench across one of the bays? I would expect at least a thin layer of finer sediment deposited under water in the middle? I guess it depends on how long they were water-filled before draining. Still a likely to trap for spores or pollen blown up from the South?

[@TheGeoModels]

Yes...just put the Swezey paper link in the description, and it should be a download-friendly link. The bays have clay in the bottom (I'm no expert on the detailed stratigraphy), and I presume folks have worked the sediments over for pollen study. I know fir pollen is present in the area, and the thought is that the region had isolated stands of conifers but was open enough for the steady winds to mobilize the sand sheets. I presume actual evolution of the bays was seasonal, and they might have been filled or empty at interval. How long they were "active" is a good question, but I think they are definitely little depocenters to preserve some details of what the Coastal Plain was like at the time (much more brisk than today!).

[@andywomack3414]

The dry-sand used with impact model does not reflect the truth on the ground. The sand used should be very fine and saturated to more accurately reflect the impact response. I would recommend the well-rounded very fine sand eroded out of the Triassic and Jurassic dune sands found on the Colorado Plateau. Ballistic ice-bergs, what a concept. More evidence against than for it seems, but still highly entertaining.

[@TheGeoModels]

wet sand is far too cohesive for kilometer-scale deformation of unconsolidated sediment.

[@johnsimms6778]

[@worldbridger9]

Hey that was really informative and I appreciete you take the time to do this. I am no geologist although I think the bays look actually quite different than thermokarsts and more like oblique impacts on viscous material being liquefied by strong earthquakes caused by massive impact(s) hundreds of miles away, minutes before an iceberg rain. The fact so many are near perfect ellipses is a very strong indicator for impacts. The overlays of the bays are something we dont see in thermokarsts and I find the elongated bays you showed further south interesting as they dont resemble ellipses anymore. So there are still many questions although these could be highly eroded or stretched by deformations. I also found the sandy rims and dune evidence interesting although I dont think that is a smoking gun. Dating studies done by Moore and others still seems anecdotal and it may be necessary to do hundreds of sections along different bays to get a more statistical trend to determine mecanisms of formation. I recall some results showed folded stratigraphy on bay rims. So to conclude: I quite enjoyed this video and encourage many more. I am still not convinced a few sandy dunes can overturn the amazing consistency in ellipticity that so many bays´ geometry have. This is a huge piece of evidence I fail to see how so many geologists brush off as insignificant. Maybe there were pultiple impacts, or airbusts, we simply dont know. But if we cannot piece it together like detectives... If we keep downplaying geologic drama shown by geometric precision... If doing so may mean professional suicide... We will never focus our research on finding the real truth. thnks and good luck, M

[@TheGeoModels]

Thanks for the comment and view! I will present even more dunes and bays in the next vid, and I think their relationships have to be non-impact to create the observed patterns. I will be curious to see what others think! We all approach this from different angles, and there is much to learn from this landscape in the age of lidar. I admit a non-thermokarst depression origin would be good, but it would still have to be non-impact and progressive to make the dune-bay interactions I'll show next. I hope you'll check the upcoming video out, as it shows some details that typically don' t make it into Carolina Bay work, whether it is impact-focused or not! Ultimately we will all improve our work by testing it against each others' differing ideas.

Yeah I agree hat these appear much more like a climate driven feature than any kind of impact really thanks to that timing and overlapping interaction side of their evolutions I don't see how any models for bays can work without requiring lots of stretching of the evidence and explanations especially as you noted the directions don't line up and their appears to be an age progression and evolution of the bay features. The more convoluted the model you need to explain a feature the less likely it is to be correct in accordance with Occam's razor. With enough convolutions you can twist any data to support ant model you want you you have to think critically to get around those limitations if you want to try nd piece the most likely explanations for something.

a couple things come to mind as watching this. regarding the dividing line where 2 bays overlap, I dont think a comparison to celestial impacts is not valid. I think if there are too many to be cosmic impacts, they would have to be secondary impacts of ice. ice thrown off of a glacial impact would be a fraction of the speed and likely fractured at a low angle I think the impact energy would be low. the direction is something to note, not all but most clusters are. the melting ice would cause an extremely flat floor. plus these things are just different. the other ones around the world dont fit to me, I dont think there is enough similarity to call them the same

It’s also quite possible the females did the hunting like lionesses today as any alpha males would be much more valuable than they are today. Look at modern society today.

Really good video, watched it to the end. I'm still a fan of the impact theroy. To me, the general uniformity of the bays doesn't compare to the naturally formed lakes. From my understanding, the impactor broke up while entering the atmosphere going SW. Multiple fragments of varying sizes struck the 1 mile thick ice sheet, each one ejecting debris differently. That is why there can be variation in the bays angles and convergence points. I can't wait for someone to put all the lidar into an AI algorithm to see what it comes up with. Not to mention thats the only way of getting a rough estimate on their number, lol. I'd love to get your thoughts on the possibility of multiple impactors! 🙏🏻🙂

[@gravitonthongs1363]

Multiple impactors are even less likely than just one. A major reason why no geologists support impact hypothesis is the huge volume and distance of large ejecta, hardly explainable with one impact, let alone many smaller ones.

I encourage you all to look at the way the "Carolina Bays" have multiple examples of places where some smaller bays sit on the rims of larger bays. Please find statistically similar examples in the "thermokarst lakes/prevailing winds models/examples." I don't see how young thermokarst lakes could form on the rims of older thermokarst lakes in this manner. This formation supports the hypothesis that the "bays" were formed almost (but not quite) at the same time by impacts. The impacts were from ice chunks from the Laurentide ice sheet and contained very little terrestrial rock or extra-terrestrial rock as the initial impact(s) were made by a comet and not a meteor.

Hmmmm i have alot of respect for the Zamora & the Cosmic Tusk analysis, but the southwest to north east sand "blown" / " splashes" & that of Alaska & Lena river delta very interesting. Comparing side by side lidars would be very useful & dating of permafrost melts with sand splashes vs Carolina bay bottom dates. The those perma frost melt lakes dont to my mind have the crisp geometry of the Carolinas nor obvious uniform orientation either. A possible explanation consistent with impact hypothesis, is multiple comet fragments impacting ice sheet {like shoemaker levie 9's 21 fragments hitting Jupiter, but tighter grouping} first impact has different point of origin to subsequent ones. So for example Delaware's POI alignment could indeed be different to Carolina's. But having said that not sure about splashes & bay overlaps if all caused in same impact time frame. Would a liquefaction shake up of perma frost lakes {by even an impact caused} mega quake & after shocks somehow make lakes more geometric? probably not but different sand box sand formulas & bed testing impacts with ice etc & shaking might provide evidence either way.

[@BrettonFerguson]

You make a lot of assumptions to dismiss possibilities. Example: Certainly if these were caused by impact hitting the ground, you'd expect them to go in deeper. While technically correct, why would they need to have been caused by a solid object impacting the ground? Why couldn't they be a comet that broke apart and sent a bunch of chunks of ice into that area. Like buckshot, but ice. They could have vaporized once hitting the ground and never penetrated, or they could have exploded above the ground, so only a shockwave hit the ground. Like the Tunguska event, only a few hundred small explosions because the comet broke up into a thousand pieces. The object could have contained more ice and zero rock, could have been more loosely held together, been different materials, impacted at a steeper angle. Many possibilities. But you just say "Certainly if these were caused by impact hitting the ground, you'd expect them to go in deeper." and dismiss the possibility of it having been caused by impact. The fact is, we know the Earth has been impacted millions of times. Many tens of thousands of times in relatively more recent history. We know the only reason the Earth isn't covered with craters like our Moon is because Earth has an atmosphere, wind, and rain erosion washing away the craters. Another Possibility: I'm not sure if you examined this possibility seriously, or just dismissed it without much thought, but if it was one asteroid made of loose rocks, maybe even ice containing many rocks, a gravel like material, or even one rock that broke into many rocks. Again it could have impacted the area like buckshot. Traveling at very high speeds most would have burned up in the atmosphere, and only small rocks impacting the ground, but at high speeds (E=MC) would have caused a large explosion, but not have penetrated as deep. In this scenario the craters would have been somewhat shallow and erosion would have filled them in over time regardless. Another possibility is, like the ice scenario, they could have been rocks, but not iron like most meteors. Maybe they were a softer material like graphite, so exploded on impact, but did not penetrate deep. You would need to model every possible impact scenario. Every possible material, combination of materials, density of materials, every angle, every speed... Literally every possibility, combined with every post impact erosion scenario. Maybe the area was covered in 5 or 10 feet of water when the pieces impacted. So the object hit the shallow water turning it to steam vaporizing it. Maybe the area was covered in 50 feet of snow, or 20 foot thick glaciers when the objects hit. There are thousands of possibilities and tens of thousands of combination of possibilities. You can't just assume iron meteor impacting ground making a deep crater like in Arizona is the only possibility. No matter how rare the other possibilities are, if they are possible, they are possible. If we are going by likelihood, then we don't exist. The Earth certainly has no moon. There are so many things about the formation of the Earth that are so remotely unlikely. Some rare combination of materials, coming from an unlikely area, an unlikely direction, hitting at an unlikely time, at an unlikely speed and unlikely angle. It would be normal and consistent with all the other unlikelihoods Earth has encountered.

Best explanation I can get from chatgpt is this: Low-lying areas on the coastal plain started to fill with water during wet periods, forming shallow lakes or ponds. This is a common occurrence in flat terrains where the water table is close to the surface. The prevailing westerly winds across the southeastern United States during this time would have interacted with these shallow water bodies. The presence of very consistent prevailing winds is an integral aspect of explaining the elliptical shape and consistent NW-SE orientation. As the wind blew across the water's surface, it generated waves. Over time, these waves pushed sediments, mostly sand, to the eastern edges of these shallow lakes, building up rims on the downwind side.

Why do you ignore that the ice sheet had retreated from that area before YD, or that they date well outside of YD?

[@taylordansmith]

@@gravitonthongs1363 outside dates could be from continuously passing through a bad part of the torrid meteor stream over hundreds and thousands of years. I also have not heard of any solid evidence that the lorantide had receded above the impact location... If it is proven then this beautiful idea is over. I just want to know! 😊🥲🤌🏼

The moment we start seeing these and other mysteries on the far side of the Moon, it will become more obvious the the mystery is only beginning.

They look absolutely bizarre...that`s for sure. I can`t see the logic in the theory that ice chunks that large survived the massive forces involved in being launched that far through the atmosphere by a space impact. I`ve wondered if very powerful space related explosions in the atmosphere could cause features like this or if these could be caused by gas eruptions related to massive ground shaking similar to sand blow explosion craters. I gotta stop thinking too much. Have you seen the pictures of the melted areas of the stone wall in Peru where two sections of the wall appear to have turned to lava and flowed or the interior steps in Egypt in front of a window look like they melted and flowed? That puzzles me to no end...especially that wall in Peru. It makes zero sense if what I saw IS a melted stone wall...and it certainly LOOKS that way. Plus there are similar things seen in Scotland.

Never seen the stuff in Peru or Egypt...I presume KZbin or Google would fix that for me!

A low altitude meteor airburst would fit the bill.

is there water in these bays, I guess I don't know wtf your talking about, I live in sc,, guess I should go try to find one of these bays
