I think that any crater in loose sediments would likely be filled in
rapidly by the same mechanisms that deposited the sediment in the first
place. You might, for a while, be able to track the crater by deformation
in the surrounding sedimentary layers, but eventually it would all even
out, leaving barely a ruffle in the geologic record. Only craters in
hard, non-disappearing rock, not sludgy mud, would have a chance of
remaining long enough for us to discover them.
