IS. TCU. EDU Content-transfer-encodinq: BIT Hi Art, in case you want to start a ruzzy [Fuzzy] creek file, Margaret Huss didn't have any further insights on the origin of this meteorite, but she did supply details the distribution which go as follows: Glenn Huss acquired about 75 grams of Fuzzy Creek from the main mass in exchange for cataloging and classifying it. He sent two small pieces of a few grams each to Wasson for analyses. Presumably Wasson still retains these two pieces but they are almost certainly hot (read irradiated). Margaret Huss retains only a very small piece (0.8 grams). The rest of the piece (64.9 grams) was sent to Vienna, when the Huss collection was sold in 1988. This accounts for bascially [basically] the entire mass. Talk to you when you get back and hope you had a good birding trip. By the way, do you have the ability to print out e-mail messages or do I need to send you hard copies of things you might want to add to the Monnig files? Ti

No full textLetter from Tim McCoy to Clarita Nunez discussing Bluff and Cedar meteorite samples confusion.NATIONAL RESEARCH COUNCIL National Aeronautics and Space Administration Johnson Space Center Houston, TX 77058 Ms. Clarita Nunez Collections Manager Meteorite Collection Field Museum of Natural History Chicago, IL 60605 Dear Ms. Nunez, July 29, 1994 I apologize for writing again so quickly after the first letter, but I have discovered some information which may be of great help to you. I had mentioned some confusion over the labelling of the Bluff and Cedar stones for which I requested samples. I have a copy of the Field Museum of Natural History catalog of meteorites by O.C. Farrington (1916). By comparing this catalog with later publications, I have been able to sort out which of the samples labelled "Bluff" are in fact Bluff and which one is Cedar. Sample No. 1461 (an 8,619 gram nearly complete stone) labelled Bluff is really Cedar. It is pictured in Plate LXIV of Farrington (1916), should you have access to this publication. In contrast, the samples numbered 173, 174, 1459 and 1460 appear to be samples of Bluff. I believe your museum uses the sample numbers in the labelling of thin sections, so these might help you identify the sources of specific thin sections in your collection. Again, I appreciate any help you can be. I understand that you are between curators, but there appears to be no other source for samples of these meteorites, as many other collections also have labelling errors.

Correspondence from Tim McCoy to Clarita Nunez, July 28, 1994
No full textLetter from Tim McCoy to Clarita Nunez inquiring about borrowing materials and taking two meteorites out on loan.NATIONAL RESEARCH COUNCIL National Aeronautics and Space Administration Johnson Space Center Houston, TX 77058 Ms. Clarita Nunez July 28, 1994 Collections Manager Meteorite Collection Field Museum of Natural History Chicago, IL 60605 Dear Ms. Nunez, My name is Tim McCoy and I am a postdoctoral research fellow studying meteorites at Johnson Space Center. You may have seen my name before, since I have collabortated [collaborated] with Ignacio Casanova. I was informed Dr. Casanova has recently left the museum and you are managing the collection. I am writing to inquire about borrowing materials of two meteorites. Along with Drs. Klaus Keil Univ. of Hawaii) and Art Ehlmann (Texas Christian Univ.), I am currently studying meteorites from Bluff, Fayette County, Texas. This fall is represented by three stones of 320 lbs. (widely distributed among meteorite collections), 30 lbs. (Texas Christian Univ.) and 17 lbs. (Texas Bureau of Economic Geology). Also found in the vicinity of Bluff are the Round Top meteorites (three stones, all in the TCU collection) and the Cedar stones. Cedar is represented by four stones of 16.5 lbs. (Field Museum, Chicago), 12.5 lbs. (Smithsonian, Washington, DC), 25.5 Ibs. (Texas Bureau of Economic Geology) and 2.5 lbs (Baylor Univ., Waco). Published literature, including the Catalog of Meteorites, indicates that the Field Museum may contain significant pieces of at least two of those. I am interested in borrowing materials from these two pieces. First, I understand that the Museum contains a large piece of the 320 lb. Bluff stone (listed as 26.9 kg in the Catalog of Meteorites). Secondly, the Field Museum should contain the 16.5 lb. stone of the Cedar fall, although this meteorite was incorrectly labelled Bluff in the 1965 catalog of the Field Museum. I would like to obtain polished thin sections of these two stones. It is fairly important that we know which piece the thin section was made from. Many of the Bluff and Cedar stones have been mislabelled and the only possibility of sorting this issue out is to examine the main masses of the various stones. If it is impossible to know which stone the thin sections were made from, I would like to obtain small pieces (< 10 grams each) of each of these stones. We would prepare a polished thin section of this piece for examination by optical microscopy and electron microprobe techniques. The PTS could be returned to you upon completion of our work. I hope you will have a chance to consider this matter and I look forward to hearing from you. I realize that this is a complicated request and that your expertise may not be in meteorites. I do appreciate any help you could provide. Sincerely, Tim McCoy Code SN4 NASA/Johnson Space Center Houston, TX 77058 Phone (713) 483-5436 FAX (713) 483-534

No full textLetter from Tim McCoy to Virgil E. Barnes inquiring about the state of the Bluff meteorite sample and Native Americans' relationship with tektites.NATIONAL RESEARCH COUNCIL National Aeronautics and Space Administration Johnson Space Center Houston, TX 77058 Dr. V.E. Barnes Bureau of Economic Geology Univ. of Texas at Austin Box X Univ. Station Austin, TX 78713-7508 Oct. 16, 1994 Dear Dr. Barnes, My name is Tim McCoy and I am currently working as a postdoctoral fellow at Johnson Space Center. I recently earned my Ph.D. with Klaus Keil at the Univ. of Hawaii. Since moving to Texas, I have been working on meteorites from Fayette County, Texas, with Dr. Art Ehlmann of Texas Christian University. I have also become interested in bediasites. I am writing to ask you a few questions which I thought you might be able to answer. 1. I have examined the Bluff meteorite specimen at the Texas Memorial Museum and noted that it has had two large pieces sawn off of it. The curator at the Museum has no knowledge of the removal of these pieces. However, a sample of Cedar from the Smithsonian is present in the collection with a note that it was received on 2/5/57 on exchange from the Smithsonian. Do you have any knowledge about the removal of these pieces or their final destination. 2. I have examined Oscar Monnig's tektite collection at Texas Christian University. I find it very interesting that none of the tektites show any evidence of having been worked by the Indians which inhabited the region. Yet, these large tektites would have made excellent arrowheads and the Indians must have been aware of them. Alternatively, tektite collections may contain only unaltered tektites, while worked tektites might be contained within arrowhead collections. Do you know of any evidence for the working of tektites by the Native Americans? I realize you are probably quite busy, but I would very much appreciate any insights you might provide about these questions. Thank you in advance for your time and effort.

Correspondence from Tim McCoy to Chris Durden, July 27, 1994
No full textLetter to the Texas Memorial Museum from an individual at the NASA Johnson Space Center in Houston regarding the Fayette County Texas meteorite.NATIONAL RESEARCH COUNCIL National Aeronautics and Space Administration Johnson Space Center Houston, TX 77058 Dr. Chris Durden Texas Memorial Museum 2400 Trinity Univ. of Texas at Austin Austin, TX 78705 Dear Dr. Durden, July 27, 1994 My name is Tim McCoy and I am a postdoctoral research fellow studying meteorites at Johnson Space Center. I am currently collaborating with Dr. Klaus Keil of the Univ. of Hawaii (from where I recently graduated with my Ph.D.) and Dr. Art Ehlmann of Texas Christian Univ. in the classification of many of the meteorites collected by Mr. Oscar Monnig between the 1920's and 1960's. These meteorites have now been donated to Texas Christian University. Our goal in studying these meteorites is both to classify individual stones and determine relationships among the stones. Often we find that meteorites collected in the same area may sample two or more individual falls, with each fall depositing numerous stones. We are currently studying meteorites from Bluff, Fayette County, Texas. This fall is represented by three stones of 320 lbs. (widely distributed among meteorite collections), 30 lbs. (Texas Christian Univ.) and 17 lbs. (Texas Bureau of Economic Geology). Also found in the vicinity of Bluff are the Round Top meteorites (three stones, all in the TCU collection) and the Cedar stones. Cedar is represented by four stones of 16.5 lbs. (Field Museum, Chicago), 12.5 Ibs. (Smithsonian, Washington, DC), 25.5 Ibs. (Texas Bureau of Economic Geology) and 2.5 lbs (Baylor Univ., Waco). It is our understanding that the Bluff and Cedar stones which were in the possession of the Bureau of Economic Geology have been transferred to the Texas Memorial Museum and are in your care. I am writing to inquire about the possibility of examining the Bluff and Cedar stones and removing small pieces (< 10 grams each) for study. We would prepare a polished thin section of this piece for examination by optical microscopy and electron microprobe techniques. We would wish that this polished thin section could remain in a larger collection (either the Univ. of Hawaii or Texas Christian Univ.), but a duplicate could be made for your museum if you so desire. I would like to call you at your number (512-471-1604) in the coming week to discuss the possibility of securing some material of these stones. If you are agreeable to such a loan, I could travel to Austin in the near future to sample material. I hope you will have a chance to consider this matter and I look forward to discussing it with you.

Correspondence from Tim McCoy to David Lintz, October 16, 1994
No full textLetter from Tim McCoy to David Lintz discussing O. C. Farrington's records of the Bluff and Mart meteorite samples and possible histories of how the meteorites were traded and sold.NATIONAL RESEARCH COUNCIL National Aeronautics and Space Administration Johnson Space Center Houston, TX 77058 Dr. David Lintz Strecker Museum Baylor Univ. Waco, TX 76798 Dear Dr. Lintz, Oct. 16, 1994 Enclosed you will find copies of information on Bluff and Mart from the "Catalog of Meteorites of North America" by O.C. Farrington (1915). Farrington's catalog summarized the literature on meteorites, as well as listing locations of masses. The information on Bluff is not particularly helpful or new, since Farrington was apparently unaware of Charlton's report of three new stones. The Bluff section only discusses the original 320 lb. Bluff #1 stone, not the Cedar stones reported by Charlton. Of greater interest to you is probably the section on Mart. In Charlton's note, he reports that a slice had been cut for the Smithsonian and a report was in preparation. Farrington reprints the publication of Merrill (1900, Proc. Washington Acad. Sci., 2, 51-53), which is almost certainly this report. Merrill reports cutting the meteorite in half and retaining a slice of 456 g. This is almost certainly the 454 g slice currently held by the Smithsonian and reported in the 1985 Catalog of Meteorites entry which I sent earlier. It then appears that the two remaining pieces were returned to Waco. At a later date (~1900), Ward visited Waco and bought one of these pieces and made a slice from the other for Charlton to keep. It seems likely that the piece Ward bought (which Charlton reported as about 4 pounds) was divided between the Field Museum (who acquired Ward's collection), the American Mus. of Nat. Hist. in New York and the British Museum (the purchase of the British Museum sample of Mart from Ward's was confirmed by the current curator, Monica Grady). Another interesting point is that you had mentioned that the recovery of Mart was accompanied by a meteor. However, Merrill notes that the surface features of the Mart meteorite suggest that it is an old fall. This may be another instance of where a bright meteor encouraged people to look for a meteorite and, when one was found, they assumed the two were related. If I am remembering your story of a fireball correctly, do any records exist of this event. As it now appears from our conversations, part of the Cedar stone and the slice from Mart were probably traded to Nininger in exchange for the Brenham slice currently on display. The Nininger catalog in 1950 listed a 563 gram sample of Cedar and a 473 gram sample of Mart. These pieces are now at Arizona State University. It will be interesting to see if the records provided by Margaret Huss (Nininger's daughter) can confirm this belief. It will also be interesting to see if Nininger acquired the 2.5 lb. Cedar stone from your museum and subsequently traded it to someone. If this is not the case, I think we can safely consider the 2.5Ib. stone lost. I will let you know how this turns out. Thank you once again for all of your help. I think it is safe to say that you have probably learned as much about your small collection of meteorites since my visit as you had since your arrival in Waco. Sincerely,Tim McCoy Code S4 NASA/Johnson Space Center Houston, TX 7705
