Hello all

Not many, I have see meteorites found in a glacial
morena and is many similar to the desert meteorites,
the same for my Lido di Venezia, found under the sand
in the Venice beach, or my Piave River found in a bad
of a river, have the surface corroded from the water
of the river, many similar to many weathered NWA's I
have see. One of these days I will go in some old
glacial moraines of the Alps and we see if I and my
group find something
regards

Matteo
