Hello Eric, Martin, All,

I'll address Eric's message first:

>Though I appreciate you enthusiasm your logic isn't that, well, realistic for good solid scientific data, especially when it comes to new falls which will most likely become the centerpiece of meteoritics in the years to come.

I'm talking about places like NWA where thousands of meteorites that
are, for the most part, already thousands of years old, are currently
being swept into piles and sold for pennies per gram.

>It's already BIG news every time there's a new fall somewhere in the world, and we've learned much more about where meteorites come from and how the interact with the Earth's atmosphere and even more about fall dynamics in the last 3 years than the entire history of meteoritics.

Right, which isn't to say that we wouldn't know more if zealous
collectors hoping to find more pieces chose to document their finds
before moving on to try to find another.

>What about news falls? Are we to leave them in the dirt to weather for a "few hundred years"? Wouldn't it be better to "save" them from the plow and rain? Or could they just sit there for a few hundred years until scientists "decide" to go pick them up?

Not at all; just take a look at Holbrooks today. Not nearly as
attractive as they were a mere century ago. Same goes for Malotas,
Gao, etc.

>Do you still think "not much will happen" to them? They will weather, they will deteriorate, and if the meteorite falls in a humid and rainy area they won't last long at all nor be of much value to science after a few hundred years. Even IF you were able to find them after that long of a period in that environment what shape would they be in. Now if they fall in a desert then that's better, but we can't really call up 1-800-Meteors and order a fireball to drop in the desert can we? ;) Now that's a novel idea... I wonder.... Hmmmm

Etc, etc. Falls are a different story, and you really only get to the
point in your PS, so I'll skip to that.

>P.S. As a side note:
Everyone should record data on ALL meteorite finds, but alas, I've
seen people simply pick up stones and walk away without taking photos
or recording coordinates of NEW falls. It's a shame, but it happens.
At least if you look at the newest falls over the last 3 years or so,
you'll see that a good majority of meteorite hunters do in fact record
all data possible and only then do they remove the stone.

Bingo. There's your problem. Even when people have the means to
document every find (e.g. Ash Creek, Buzzard Coulee, Park Forest,
etc.), not all people do! It's one thing to say that it's not
plausible to document every NWA, but when it comes down to it, there's
no excuse for not documenting stones when, if you're willing to make
the effort and responsibility to hunt for rocks from space, you're
choosing to *not* make the effort to document your find as well as it
should be done. It's simply irresponsible.

So, to reiterate - I'm not advocating leaving fresh falls on the
ground, but when it comes down to it, as I said before Jeff even said
it - perhaps we should have some sort of a regulatory/qualifying way
to judge and permit meteorite hunters before they go out into the
field. It would make a lot of sense...

I agree - terrestrial history is undoubtedly less important than
extraterrestrial.

My problem is that you're willing to take the terrestrial/entry
history and erase it, just like that.
Most NWA's are very old; they would not suffer if they were left there
for even centuries.
If we left them until the time when we could go there and properly
document them, they would not suffer.
You say that it is worth it to pick them up *now* so that we get the
extraterrestrial data and lose the terrestrial data.
I think that it would be better to wait the extra few decades so that
we might get both sets of data.
You have yet to explain why you think that it is worth it to pick them
up now as opposed to later in exchange for the loss of all
terrestrial/entry data.

> Not a year of the last both decades, were not new meteorites with absolutely

And if we were taking things more slowly and recording, those stones
would still be recovered later. They would.
And we would find more stones paired with them, but maybe not right
now. Maybe in ten years or twenty.
But we would find them eventually if we kept looking, and we would
probably find more if we decided to hunt the areas thoroughly. But we
do not know where NWA 5000, 482, 011, etc were found, so we cannot
look for more.

Wow. Really, Martin? I've been doing this for how long and you don't
think I can rattle off the percentages of stony to stony-iron to HED
finds and falls, etc?
Now you're just being a jerk...

Ah, that's where we differ in opinion.
I've been to the labs and seen what they're doing. Yes, they get many
new meteorites to analyze thanks to the NWA rush, but if you look at
most papers...they don't describe new meteorites. They describe
features or studies performed on previously studied meteorites. I
spoke with Alan Rubin a while back at UCLA - we were looking at a
large poster-sized photograph of a thin section of Semarkona. As he
said, he could spend many lifetimes analyzing the countless chondrules
in the photo, probing each and every relict grain to determine its
thermal history...

Scientists don't need more, more, more.

Yes, it's great that they're getting so much material to work with,
but, hell - they can't even get through all of the Antarctic material.
 There's too much there already.

You say we need to find more to advance science. I agree. But I
would advocate letting off and letting science catch up to us a little
- and in the meanwhile, preserving the terrestrial history of the
stones that we can - instead of simply grabbing what you can while
you're alive.

Because that's a very egocentric perspective.

It's happened before us, and it will happen in the future. I see no
reason for you to say such a thing.
You might as well say that people will stop collecting minerals or
fossils, or lose interest in geology altogether.
It's a very strange thing to say.

It doesn't take an "official expedition" to document finds well. It
takes someone with a cheap digital camera and a GPS. You keep
insinuating things that don't make sense.

Well, they have, actually...though the WAMET and EUROMET folks haven't
been down there in a while, they did find nearly a thousand meteorites
in Australia in the early 1990s.
But those meteorites, in some cases, have been there for upwards of
35,000 years. And they *do* do a pretty good job of chasing down new
falls using their camera network.
I just don't understand this rush of yours. They're rocks. Yes, I
understand that falls weather, etc, but the vast majority of
meteorites are already weathered. Sitting there for another few
decades isn't going to to much, if anything, to them. Yes, I would
prefer to see more meteorites on the market, but if it's the choice
between an stone with coordinates or a stone without them...well,
that's not much of a choice, is it?

Honestly, I'm amazed more than anything. That strewnfield was
*discovered* by scientists!

http://www.myfoxaustin.com/dpp/news/021909_Meteorite_Pieces_Located_in_West_TX

Some people sure have bad memories....
It's true that most of the stones found were collected by hunters and
collectors, but perhaps that's simply because it was a common
meteorite, rather uninteresting to science, and it had a high price
tag.
Compare to 2008 TC3, where scientists went all the way to Sudan to
recover specimens.

But almost all Omani meteorites are recovered with data anyway, so
that's kind of pointless. They're gathering data, but no more than
would already be gathered by collectors over there.

Right, but you're just saying unrelated things. This has nothing to
do with why NWA finds shouldn't be documented.

Due to a lack of education, probably, but yes...

And there's no reason to say that it won't. Unless, of course, there
are few meteorites left to be found.
Then they couldn't, even if they had the means.
Which is what I keep saying. There's no reason not to wait, because
once you pick that rock up and bring it to Rissani, you don't know
where the hell it was found. And it wouldn't suffer for sitting in
the desert for another twenty, or even two-hundred years.

Again, you're being a bit of an a**.

Education at its best.

Even you use the word "hiatus." Hiatus means a temporary reprieve.
Temporary.
And using it, you seem to want to imply that, once recovery has
stopped, it will never recommence.
The trouble with this break is that it is happening in large part
where collecting was already being done by motivated hunters who *did*
document finds well. Canada and Australia were not the problem. Oman
is not the problem.
NWA is the problem. That's where meteorites are losing their
identities, and that's where we need restrictions.
I say let Canada and Australia 'go free.' Allow responsible hunters
with GPS' and cameras to hunt. But there's no excuse for this highly
unscientific recovery of meteorites from NWA so that we can get as
many samples into labs as quickly as possible.
Well, unless you're a dealer hoping for a new lunar.

All I could find online was that an Antonio Silva discovered the first
stone, and that locals subsequently recovered others. Not sure what
your point is here.

And if we hadn't, in almost all cases, those meteorites would still be
sitting in NWA, intact, and with their coordinates as well. Waiting
to be found by someone with a GPS. Someone who could come back and
reliably hunt for more in a thorough fashion.
In a few decades, we could easily have twice as much or ten times as
much of this rare material than we do now. Maybe we will. But if we
do, pairings will be unknown, and, assuming that some meteorites are
actually heterogeneous, much information will actually be lost.

I keep acknowledging it, but at least now you're finally saying that
it's more important to you to have them *now,* which is a statement I
can't agree with.

>>Well, it's keeping some out.

Some people are stopping going to Oman, some people are choosing not
to hunt in the US, and many are choosing not to hunt in Australia.
But many are choosing to continue to go to these places to look for
meteorites.

Depends on the country - some allow you to own, some not to export,
some to export with a permit, some pay you for them, etc. So saying
that the laws discourage hunting....look at Neuschwanstein, look at
Grimsby and Buzzard Coulee. Such laws don't seem as discouraging as
you suggest. And coordinates were not misrepresented in those places;
you would have to make them very false in order to change the
*country* in which they were found.

Well, assuming that those known fields have been hunted out, you're
lamenting the loss of nothing, really.
I suppose not being able to hunt legally, which I've already said, in
a place like that I don't particularly agree with because of the fact
that most meteorites there were being well-documented.
Though there are many examples of falsified coordinates, etc., which
is something I do disagree with.

Well, there is a team out there now, so that's not true. Granted,
it's only one team, but one team can recover many stones in a
trip...and it's not like they're going anywhere any time soon. Oman
is another place where most stones are very old, and while science is
undoubtedly the better for them, perhaps it would be better if people
didn't lie about where they found them. Perhaps it would be better if
it took longer for a scientific team to recover the material and
information weren't falsified.

It's not as though the material wouldn't still be waiting to be picked
up with coordinates if we didn't have it yet.

More, more, more, fast, fast, fast. There is no reason for this. I
agree - more is better. But when you lose documentation, I would
favor taking our time and actually recording where they were found
instead of using, again, basely unscientific recovery methods. Those
rocks would still be there, waiting to be picked up - another fact
that I keep saying and that you keep ignoring.

Now that's something I think we can all agree is waaaayyyyyy over-optimistic.

I admire such lofty goals, but the incentive to find new and rare
material is money, not science. Hence a lunar sells for more than an
LL3.1, and hence, people try to find lunars. Unequilibrated material,
while it is still valued, is what tells us so much more about the
early solar system. And it's worth a mere fraction of the other
stuff.
Go figure.

Accept it? Well, no, I don't have a problem with that. I understand
what it's done for the science of meteoritics, etc. What I dislike is
the commercialization of the hobby to the extent that science actually
winds up the worse for it, which is what you don't seem to have a
problem with.

Right, and they typically did a good job of recording their finds - so
great. My problem is with NWA, and with irresponsible people who go
to Ash Creek and Buzzard Coulee and don't GPS and photograph stones in
situ.

Well, take inflation into account. $1000/g nowadays is actually
cheaper than $100/g in the 19th century.

I don't know number of each - all I know is that there are many
hunters at places like Franconia and Gold Basin who go to look for
meteorites and who don't care to take a GPS or camera, and they're
starting to go cold-hunting. Many of them have little incentive to
record coordinates.

Well, we do. All it would take is a GPS, pen and paper. Not much
infrastructure.

It could easily be financed. GPS' cost as little as $50 nowadays.
How much money did you make off of your last lunar? Enough to buy one
or two and change your profit by 1%? If every dealer and did that,
they would all have GPS' by now.

It wouldn't make a dent.

That might make a difference, but I'm busy enough here trying to
double-major, in clubs, working in a physics research lab here,
so...yeah. Maybe if I go into meteoritics in graduate school it would
make sense, but there's too little in the way of meteorites here at
Berkeley to warrant suggesting such a project because there are no
professors who are that into meteorites to back it.

Oh, it's not a money issue. It's a politics issue and a priorities
issue. I think that would be really fun, but I'm already committed to
a project here working on meteorites. The fact that you're making the
kind of argument that says "if you care so much, then why isn't your
life devoted to the cause" means that you've really nothing to say
against the idea, though, because you've stopped questioning it. So I
guess it really does have some merit.

Clearly.

They would always have had enough for that. I'm against this surplus
where there are too many to be classified and they can only analyze
the rare ones because there are so many OC's that they can't deal with
them all. That's a problem. And the lack of coordinates is a
problem. And in the long run, we will have less material to show for
it because we have not hunted thoroughly and mapped out strewnfields,
etc. And this is where we disagree- I say move slower and more
thoroughly. You say move fast, take what you can, and move on.
Science doesn't work like that.

No. I'm more interested in the solar view of things as well.
But I acknowledge and value the terrestrial aspect of their history as well.
Saying that I believe it should be preserved doesn't mean that I think
it's more important. I just think that it's important enough to
warrant saving.

Any real scientist would.
