Did the meteor or comet that struck Earth at the end of the Cretaceous punch a whole in the crust down to the mantle? If so, why isn't that part of the crust weak and showing signs of volcanism? Even if the crust wasn't punctured down to the mantle, wouldn't it still be a weak spot and show volcanic signs -- sort of like "hot spots".
