Hi Jonathan,
The Catalogue of Meteorites lists 29 from North Carolina with 8 of those
being falls.
Good hunting,

From the outset, let me say I do not think there
is any reliable evidence that there are
extraterrestrial intelligent visitors (ALH 84001's
possible microfossils sure didn't look like they were

Having said that, there are still mysteries to be

Elton, Thanks for the explanation. It amazes me how knowledgeable the
members of this list are and how willing you are to share that knowledge.
Now, one more question. If I'm out collecting Apache Tears and I should
pick up a Tektite, how would I know the difference? If I happened to put

their third and last live webcast, accessible

Here's an idea. Why don't we all just vacate this list en masse? Then
we can create The Meteorite Central Meteorite List: The Second

Hi,
Obsidians have hundreds to thousands of times more water in
