Hi Michael and list,
Great pictures! Has any one been to the Sikhote-alin strewn field to
hunt meteorites recently? Or is this area still of limits to hunting?
Thanks,
Sonny

Hi all,
Most of you have probably seen it already but for anyone following this
thread there is footage of a couple of trees in the Sikhote-Alin
documentary
where pieces have gone clean through them. It's at about 6:08.

Cheers,
Jeff

I don't think the heat was from the small meteorite itself, but the
kinetic energy released by the impacting bodies. There was enough
energy
to form craters/pits that were 20-30m wide and down trees.
Like in all cratering events, there was a hot air blast caused by the
energy release which may have charred the outside of the trees.
This is just a possible way to explain the charring, if in fact, that
is
what I am seeing on the bark of the tree (again, not behind the small
meteorite).

I don't see any charring...only staining/rust. <<
Wanting to expand a little here...assuming the tree was alive when
struck,
I don't think a small meteorite would carry enuf heat to cause any
charring that would be noticed today. Being one who relies on a
woodstove
as their
primary source of heat, I can attest that it's a real bear to get
wet
wood
to even think about burning. If it was a dead tree, I still doubt
there
would be enuf heat in this small piece to cause anything to burn. If
a
small
piece was hot enuf to cause any charring, I can only imagine how much
heat
would be in the larger pieces...were there any burnt trees in the
strewnfield area? I can't tell from the photograph, but was this
piece a
fragment or
an individual?
