[meteorite-list] Shattercone?

[Bernd V. Pauli]

Hi Larry and List,

Larry asked:

"I found this interesting rock close to my home in Lapeer County 
 Michigan while walking in the woods this past September."

It sure does look like a genuine shattercone! Congrats! It might be
a shattercone from the Sudbury impact but another possibility might
be the Serpent Mound structure in Ohio from where shattercones and
coesite have been reported! Maybe Paul H. (oxytropidoceras at cox.net)
has more on that!

Best wishes,

Bernd
