Hi Matt,

What a cool piece to have in your collection. How did you ever find it?

P.S. If you ever want to sell it, put me first on the list!

Sonny

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?
