Hi,

        I think the characteristics I described are seen one "larger" (over
20 grams) specimens. It is going to be fun to see what meteorites and
science will come from this fall.

Thanks,

Peter

Hi Count....strange that yours do not have any of the brown crust or other
surface features common in most from the fall that were picked up within
days.

three different foreign sources resemble themselves. The specimens I have
look like they could have come out of that pile that Mike Farmer posted.
Mostly small individuals of less than three grams, black even fusion crust,
no other coloration, regs, no cracking except for a few fracturing in flight
with the result that the interior lithography is covered by black fusion
product. None but a few that I've seen so far show more than the smallest
impact marks and those display a typical grey chondritic, almost Portland
cement color. Most landed on snow so have remained pristine. Heavier pieces
will be recovered when the ice and snow melt. They are strongly attracted to
a neo magnet and set off a detector easily, so I'm a little curious about
the initial classification I've heard. Is LL6 S1 W1 and named
Chebarkuhl..correct? Anyone...Ted?
