What are you identifying as Flood deposits? ICR seems to consider
Precambrian as created in place and Cenozoic as post-flood; both contain
impact craters.
I have not read much of the 3rd edition (I only glanced at it to confirm
that flagrant historical inaccuracies were not corrected), but Scott Huse,
in the second edition of The Collapse of Evolution, denied the existence of
ancient meteor craters.
The Chixulub crater is the only one clearly associated with major
extinctions; other extinctions are not clearly linked to craters and vice
versa.
