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,

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?
