Hi, List, Robin,

    You ask:

> any information about the Cosby Creek Fall?

The NHM Catalogue of Meteorites says:
    "Two masses, one said to have weighed 2000lb
and the other 112lb, were known before 1837,
G. Troost (1840); C.U. Shepard (1842, 1847).
    The larger mass was forged into various articles,
V.F. Buchwald (1975). Distinct from Waldron Ridge
( q.v._ ) and Greenbrier County ( q.v._ ).
    Analysis, 6.57 %Ni, 91.5 ppm.Ga, 431 ppm.Ge,
2.9 ppm.Ir, J.T. Wasson (1970). Analysis, classification
and origin, B.-G. Choi et al. (1995)."

> Any samples? Are they ever traded?

    Well, there's one on eBay right now, starting at $0.01:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110107596539

    And, if you're in a more expansive (or expensive) mood,
etched whole slices are apparently available at $4 a gram:

    Next...

    Let me tell you about this wonderful thing called
Google... For example, if you Google "meteorite
database," you will be rewarded with an armload
of internet databases about meteorites with more
information than a mind can hold, starting with:
http://tin.er.usgs.gov/meteor/ , which is always a
good place to start.

    A meteorite has to be tough to survive in Tennessee
I guess. Of 26 Tennessee meteorites, 21 are Irons (only
one was a Fall), 2 are Mesosiderites, and only 3 are Stones
(Drake Creek, a witnessed Fall in 1827; Petersburg, an 1855
witnessed Diogenite Fall; and Maryville, an 1983 witnessed
Fall).
    Tennesseeans do not seem to notice rocks falling from
the sky very well, nor meteorites lying about the landscape,
but they are powerful good at ploughing them up! And East
Tennessee is replete with Irons from the early 19th century.
    Every spot where one (or two or five) meteorite(s) fell
is an excellent spot to look for more! Assuming you could
locate these old Iron Find locations, that metal detector might
prove useful there.
    On the other hand, Kansas is flatter... a lot flatter.

Many thanks to several of you profound students of the heavenly rocks, you
are all right on the button! Yes, there are several other postcards like
that one that are properly identified, but of course none have the
detailed information like you all have presented me. Makes me want to
really go to Kansas and see if I still have any farming friends out
there.... and take my detector of course.

Now, on the other topic I presented... Does anyone have any information
about the Cosby Creek Fall? Any samples? Are they ever traded?
Any information about how they were found?

What about the Harriman finds?

Im interested as you can see mostly in finds in East TN.

Thanks again,

Robin
Knoxville
