[meteorite-list] Question on new NWA 2828 paleometeorite

[Bob King]

Hi all,
I can't help but wonder when I look at the new paleo EL3 offering by Greg 
Hupe (likely the same as Stan's fresh EL7 slices and Marcin Cimala's yet-to-
be classified MC024) how anyone suspected it as a meteorite in the first 
place. It was underground, stuck to rhyolite cobbles, shows no crust or fresh 
metal. How was it identified? There must be an interesting story in its 
discovery. Anyone?
Thanks,
Bob
