Hi Larry,
This looks pretty good to me. While is is always hard to judge by photos it
looks consistant with Sudburry. I have collected shatter cones in New
Mexico at the Sante Fe site and have a number of others including Sudbury in
my collection.

Subject: [meteorite-list] Shattercone?
Hello List,
I found this interesting rock close to my home in Lapeer County Michigan
while walking in the woods this past September. It looks like a shatter
cone to me but I've really no experience with them. One peculiar
characteristic of the rock is that it's not smooth. All the rocks here
have been smoothed and rounded during their glacial transport. I wonder if
it's from Sudbury and was relatively close to home so it didn't have to
travel very far and didn't erode too bad?
I did a few internet searches and didn't find any reference to impact
debris being found in this area.
Any shattercone/impact experts out there?
Comments and thoughts appreciated.
