Hi Chris and List,

That is an interesting number - 4 out of 57.

At one time, all 57 craters had meteorites. One can assume that
terrestrialization takes it's toll over time, but to have surviving
meteorites at only 4 craters is interesting to me. Without looking at
the crater ages, I bet those 4 craters with meteorites are iron
meteorites, or recent "fresh" craters (Sikhote Alin), or both.

Unless the rest of the craters are ancient, or were created by friable
types of meteorites, there should be some meteorites hiding in some of
the other 53 craters.

Best regards,

MikeG
