Hi Jeff/All,
Thanks to those who replied to my question about survival of Chondrites
in wet climates. The Pultusk, found in 2006 after more than a century in
a wet climate, is an excellent example Jeff.
Great pieces Marcin.
I suppose that means that larger pieces of Barwell may still be around
in reasonable condition....although Barwell is probably more fragile and
an L chondrite rather than an H....or perhaps that means there is less
in the matrix to rust and weather the meteorite away. We know more about
what to look out for now.

Hi Graham, Göran & all,
I believe Pultusk would be another good example. Here's an example that
Marcin has:

I changed the subject as this topic took a different path from the
original posting.
There are strong evidence that the Ultuna meteorite found in 1944 is
paired with the 1869 Hessle fall. Classified as H chondrites. I don't
know the weathering grade of Ultuna.
I had the happy coincidence to handle a large (about 600g) individual
this winter.

Great pieces Mike....looks like this last month has been a good one.
Hoping to get to Ensisheim or Saint Marie again this year...but not sure
yet.
And now a question Mike...or anyone else out there. Are there any
records
of chondrite falls that were found many years after the actual fall (40
or more years) in climates which are wet or similar the Britain.
I am still trying to asses what sort of state a meteorite such as
Barwell
may be in after weathering the elements for that long as we are still on
the track/hunt for one large piece observed to fall by a farmer well
outside of the normal strewnfield but never recovered. Are there
instances
of such finds, and if not, is it because they have weathered a way
completely?
Any thoughts anyone?
