Hello, my name is Robert, I’m an archaeology graduate. I study tornado archaeology, and detecting tornadoes prior to the written record through archaeological methods. I also study how tornadoes have impacted settlement depopulated in the Southeast through the past 800 years.

There’s a few big ones I haven’t tested like the Moore tornadoes, Joplin, and the main Greenfield tor. Tornados in more urban environments that didn’t impact patches of trees are nearly impossible to find, at least with my methodology. It requires undisturbed forested soils.

A quick post on the top 10 most intense scars I’ve tested: 1. A likely Mississippi scar from the 1500s. 2. An undated Tennessee likely scar 3. A likely scar from the 1700s in southern Indiana 4. The Guin 74 scar 5. Sulphur Rock AR 1929 scar

@mee_wx Maybe, but I doubt it. You need a decent amount of undisturbed land to be confident you’re looking at a scar, which is why I target national and state forests usually. Even things like plowing destroys the scar. This seems like a pretty populated and disturbed area.

I wonder, what the fuck happened here in 1682. I was looking through ct tornadoes and all it said was "locals reported a 3/4ths mile wide swath of downed trees. Is there a way that you could find the scar?

@JigsawYessir @Roman2413045124 @EMoriartyWX I specifically target national and State Forest for their amount undisturbed land. I need a couple miles of disturbed soil to test for scars. Or at least be any confident they’re scars and not some isolated event.

@JigsawYessir @Roman2413045124 @EMoriartyWX I kind of just test randomly in undisturbed soil locations. Sometimes I’m looking for a specific historical tornado, sometimes I’m just testing an area. I’m sure there’s dozens of scars I haven’t found even bigger.

@t0rnadofx @Roman2413045124 @EMoriartyWX I’ve got a lot about it, trying to include it in my thesis. I’m just trying to figure out how to frame it as it’s so out of place concerning other data. I want to try and give it some wind speed estimates, but my preliminary stuff is frightening. Like 400mph+.

@aa16126928 @HollandMiSpouts I believe it was called Lewis state forest? I think it was a bit from Columbia I don’t remember the town it was nearby.

@crossroads44880 I have lots of records on each tornado and potential tornado, all of it comprising my thesis which I will be defending soonish if I’d stop having new ideas. 😅

@Trough_Digging This popped up on my feed and I love this so much. I hope you are writing this information down in greater detail somewhere for future recordkeeping. How fascinating, I think this has lots of potential!

@Roman2413045124 @EMoriartyWX But that O lens can tell you a lot. Soil particle size can tell you the intensity of the mulching that occurred and a fairly simple microscopic analysis can tell you if it’s hardwood or softwood mulching.

@Roman2413045124 @EMoriartyWX Not too much to show pictures of sadly. Just buried O lens’, so a thin darker strip about 20cm down in soil probs and then a few cm of less organic soil above that-as the natural biodegradation of the forest stopped since there were no trees for a few decades.

@Roman2413045124 @EMoriartyWX The only other thing I can think of is some sort of Native American activity but idk why they would want several sq km of unburnt fine mulch.

@Roman2413045124 @EMoriartyWX To the point that I wonder if it’s some sort of testing issue but I took 12 samples in the scar and all showed the same thing. I’ve tried to think of alternative hypotheses but nothing makes too much sense. What else could fine mulch several square km of forest?

@JoshPateCFB The amount of organic matter correlates pretty well to the degree of wood chipping caused by a tornado, which in itself is one of the best indicators of strength. So far it’s correlated very well with NWS strength estimates.

@JoshPateCFB Here’s a short explanation how it works:
RobertWx@Trough_Digging

@HrizztoWX Lots to explain over X, it will be published with my PhD thesis showing how it’s done, but I’ll do my best to give a shortened version. When a tornado hits a forest area, something called splintering occurs, when dozens of trees and branches break in an area it makes…
