Why would it be such a coincidence that this impact happened at the time of the Younger Dryas? I can't remember how many 500 year weather events have happened in my lifetime.

That said, it looks like a lot of work remains to be done to research this crater.

:') Some days it sure does feel like 500 years, eh? ;^) It does date that way, there's an explanation of how that was figured out (has to do with the way the "splash" is distributed when there's a big impact on ice).
