Hi Darren,

Some of my shots show that that may just be the case as mentioned in my
post just....pic 17. And my piece has this black surface traveling over
its 3D surface in several planes...they are not just flat.

The Bolivian group who visited the site soon after the fall have pieces
of around 1kg and 3kg which apparently are heading for Japan at this
moment! I have been trying to get photographs of them sent out...but no
luck yet. Lets just hope they're rough with them during shipping eh!
;-)
Then we might find out.

Anyone out there have pictures of other meteorites that show similar
features to compare...did Park Forest have such veining?
