Hi Rob, Greg,

That really does look like a fall; beautiful stone.

It reminds me of Bensour a bit, although I didn't see evidenve of brecciation which is pretty prominent in the Bensour I have seen. Any chance it could be from that fall?

Regards,
Jim Baxter

Hello Rob,

That is a very nice and fresh stone. I would say it does not represent any
of the recent NWA falls. I would send it in to have it classified, and
request the classifying scientist to have the terrestrial age dating
performed by an approved lab. Obviously it will not get a distinct name
without witnesses and GPS coords, but I think that it would be worth
classifying.

Good luck with it!

Best regards,
Greg

> It has a lot of free iron (more than visible in the photographs) and few

> Based on the free iron, I would not expect it to be LL like Bensour.
> Tested with a magnet, it is attracted strongly, but slightly less than
