[meteorite-list] Shattercone?

[MEM]

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.
