I found this specimen in 1998 and it was one of the larger ones at 775 grams. It was found at a depth of 3 feet.

It has a terrific pattern that is all and all Glorieta. Also, I see in the photo of the etched surface along the edge what looks like an "a2" zone.

This is caused by heating and is a component of the fusion crust. I think in irons the crust is divided into three components. 1) and oxide coat. 2) a melt zone and 3) a heat alteration zone.

If my what I see is correct then the heat alteration zone is visible along the edge of this specimen.

What a beauty it is!
