Zero expertise in any of the related disciplines to interpret or judge any of this, but I can say with confidence that the related Wikipedia page https://en.wikipedia.org/wiki/Younger_Dryas_impact_hypothesi... is a wild read and outright flamethrower at everything about Younger Dryas and seemingly, everyone involved.
The Younger Dryas theory supporters is controversial across multiple disciplines because it challenges the idea that human progress has always been linear (gets better over time).
Some believe that ~13,000 years ago, humans were highly advanced, but a massive flood (Younger Dryas) wiped out & reset civilization.
Supporters of this theory often point to two things: nearly all major religions reference a great flood, and there’s a current lack of understanding how ancient megalithic sites were built with tools thought to be available at the time (primitive bronze tools, etc).

Unfortunately, it seems like folks from both sides of the topic talk-past each other ... and at least I haven't seen a balanced debate on the subject. If someone has seen a balanced assessment, please share.
Look a lot of this passes the sniff test but anything Younger Dryas related I have to assume based on past performance is all buillshit designed to prop up religious fundamentalists and bodgy history.
How is this supposed to work with the sedimentation? The glass spherules under the lake are maxxing out 5-6 meters below the surface. Where does the material on top of that come from, and why didn't it fill in the lake, but leave it intact & with ridges?
Second, if you think of an impact at an angle, the crater and its ridges form an ellipse. If its coming very flat, the structures might look rather parabolic, but still bent inwards. In the article, the north ridge is bent outwards. How? Questions over questions.
