Hi Bill,

You have a most interesting specimen, especially the brecciation. However, the regmaglypts don't quite look right. With the high polish the stone appears to have, they look more like ventifacts.

Sincerely,

> #3 This stone has regmaglypts
> #4 This stone has small pits from micro meteorite impacts
> #5 This stone has chondrules and found 1 with metal rim
> #6 This stone has VERY TINY metal flakes inside, not very many, but
> they are there. It is VERY weekly magnetic
> #7 This stone has no, or very thin, waxy, fusion crust with a green
> tint to it. Surface has a FEW small vesicles
> #8 This stone has been visually examined by several geologists,
> meteorite dealers, 1 physicist, and a Representative from the Cascadia
> Meteorite Laboratory, and the consensus is that it is for sure a
