That brings up another thought-- with a magnet or metal detector, you'll find the loose metal parts
of the meteorite, but what about the loose olivine crystals part? Those fragile, shattering
portions should have flinging out a rain of olivine crystals. Anyone ever take some of the soil
from around any of the finds, scoop it onto a screen, run a hose over it, and see if you come up
with any loose crystals? Maybe not as cool (and valuable) as finding the big iron, but it'd still
be interesting to me, at least-- (I have no practical expereince meteorite hunting, but when it
comes to spending many hours sifting through sand for tiny shells and fossils, I've BTTTGTTS, see
