[meteorite-list] Crater maker

[Michael L Blood]

Thanks to all who responded.
        Other than the 10 to 1 ratio, I pretty much thought
the same as what most people stated.
        Here is what I did respond with:
--
One "formula" in which I hold very little
belief, is a ratio of 10 times the diameter of the
impactor. This question has far to many variables, such
as speed of meteorite upon contact, type of soil
and composition of meteorite (ie, stone or Iron),
angle of trajectory, etc. In addition, the K-T event
produced a crater (as indicated by hypercompacted
quartz) with a diameter of 500 miles - but the impactor
is estimated at "only" 6 miles in diameter - the ol' 10
to one ratio implies there should have "only" been a crater
60 miles in diameter.
        Best wishes, Michael
