I think that pictures do not tell the entire story.

The Winona Meteorite is primarily silicate with large
areas of oxide where metal or sulfides or such must
have been present.

On the exterior it looks almost exactly like Meteor
Crater oxide.

And this has made me, and other wonder if in fact the
Winona Meteorite is related to the meteorite that made
Meteor Crater.

I think that it is.

ALS0, I think that all of that iron shale that has over
the years been tossed as worthless, should be looked at
again.

Any piece that looks different is some way from the
"normal" iron shale should be cut and examined--
especially if it has the distinct green nickel oxide
stains that Winona has.

(And having seen countless pieces of Meteor Crater iron
oxide- I remember having seen pieces with green
stains-- they are rare compared to the much more common
types of iron shale)
