List, Elton,

Thanks for the comments, input and congrat's people.

  I still have a lot of questions regarding origin though and why it
hasn't been smoothed from glacial transport. I doubt it's from mining
since there isn't any of that going on in my area other than gravel. We
have many gravel and sand pits due to the glacial activity that pushed
and piled up rock and sand only to retreat and leave huge mounds that
are now the hills of my area.

The exact coordinates of the find are here.

43 00'06.58"N 83 22'17.85"W

Can a particular shattercone be linked to a specific event?

Sincerely,
Larry Atkins

It would help to have the exact coordinates and circumstances as a
substantial
area of the UP of Michigan is a giant mining network. Given this fact
I cannot
rule out a blasting artifact but can't rule out a shatercone either.

A formation/deposit was recently identified in Michigan which was
impactite from

Sudbury. I have samples in study from another "misidentified"
formation which I

believe it from Sudbury.
