Meteorite Times MagazineA Grand Meteorite from a Grand Houseby Martin Horejsi

The Grand Meteorite.At over 1500kg, the only thing more impressive than the residents of Casas Grandesmoving the meteorite is the reason why they did it. However, that missing link ofinformation can only be speculated upon.

Of note on this slice are 1) the obvious specimen number painted on an external (akacrusted) edge, and the border where the etch is lighter. A common practice in the pastwas to mask the rim of a slice so the intended etching was encircled with unetched orlightly etched surface.

Page 5: Meteorite Times Magazine
Page 6: Meteorite Times Magazine

The specimen identification number painted on this slice is from the Helsinki Museum inFinland. The style of a blue background with white digits is like a fingerprint. Nomistaking where this slice spent time.

Page 7: Meteorite Times Magazine

A painted specimen number is made even better when it comes with the appropriatepaperwork. In this case, a nicely printed specimen card with matching ID numberprovides a deeper collection context rarely available these days.

Two more views of my etched slice showing both sides. The fully etched side, in myopinion, was etched much later than the side containing the rimming. You can easily seethe difference in etch quality as well. The longer the acid remains on the slice, thedeeper and more contrasty the etch. But passing a theoretical point of no return, youcan ruin a perfectly good slice by dissolving away too much material.

It’s fun to consider what was going through the minds of the ancients whofirst brought this massive iron into captivity. Even though we are manycenturies away from the people of Casas Grandes, the iron meteorite thatbears the same name is a showpiece in the Smithsonian’s museumdisplay ogled by thousands of people each year. So as we move togetherinto yet another year, take a moment to say thanks to those who walkedbefore us preserving the magical stones and irons we so love. If it weren’tfor their dedication and sacrifice, so much of what inspires us today wouldbe lost forever.

Until next time.

Meteorite Times MagazineThe UCLA Meteorite Galleryby James Tobin

I got an email that there was to be a grand opening celebration and ribbon cuttingceremony at UCLA for the new Meteorite Gallery. It was taking place the next day.So I got my camera out and charged a couple batteries and put about 50 gigabytesof SD cards in the camera bag and rearranged my schedule. It was the opportunityto finally get to meet a few people who over the years have been really helpful incharacterizing meteorites for me and the business. I could actually thank them inperson.

Friday afternoon traffic up in West LA is always a nightmare and they are working onthe freeway so I gave myself plenty of time and it took quite a bit of it to get there. ButI did arrive early enough to walk around a little and get the self tour. I saw someequipment through widows in doors. I really just was snooping around. I saw thegeological maps and charts lining the walls and thought “I studied this stuff back inthe paleolithic.” I went up to the forth floor and past Dr. Rubin’s office. Then a coupleminutes later actually came around a corner and saw him. I greeted him and walkedfor a minute down the hall with him. Just before a big event is not the time to have achat.

Page 16: Meteorite Times Magazine

I always feel a little out of place at events with lots of dignitaries and I was reallyhoping that there would be someone that I knew at this event. I was there to cover itas a journalist, but it is more fun if someone is there to talk to.

I made my way to the meeting room a few minutes early and picked up my nametag from the table where they were already printed up waiting. Clipped it on andentered the room. John Wasson was there and I reintroduced myself to him. Wehad spoken years ago but only once. He too was off in a moment to prepare for theceremony. I had seen Nick Gessler walking in the hall earlier but had not greetedhim yet. As I was thinking that he might be the only person I really knew at the eventJason Utas and Michelle Myers came in. Jason is a student at UCLA and working inthe department now. He is clearly having fun and enjoying learning to use theequipment.

Page 17: Meteorite Times Magazine

After several speeches and introductions it was time to move to the MeteoriteGallery and behold what wonders they had decided to bring out of the darkness ofold cabinets and into the light of display cases. I am a sucker as most readers knowfor anything Meteor Crater related. UCLA has another of those wonderful earlyCanyon Diablos that were sent around the world in the first few decades after thecrater was recognized. Their specimen is called the Clark Meteorite as it was amember of the Clark Library that they were given decades ago. UCLA has had theClark Meteorite since 1934 which is about the same length that Griffith Observatoryand The Natural History Museum have had theirs. It is the centerpiece right nowresting on a low stand in the middle of the Gallery. Weighing in at 357 pounds it is abeautiful Canyon Diablo the only touch meteorite so far in the Gallery.

Page 18: Meteorite Times Magazine

50,000 years ago an asteroid slammed into what would later be central Arizona creatingfamous Meteor Crater. The Clark Meteorite seen at the UCLA Meteorite Gallery is a verynice naturally sculptured piece of iron from that impact event.

The UCLA Meteorite Gallery is dedicated to providing information and educationmore than any other museum I have been too. Usually you will only see the name ofthe specimen perhaps the type and maybe if you are lucky the weight. At the UCLAMeteorite Gallery you get much more information. You get to learn how the differenttypes of meteorites relate to one another and about their places of origin and theparent bodies where they formed.

Page 19: Meteorite Times Magazine

The UCLA Meteorite Gallery offers a rich learning experience with much more in-depthinformation about the meteorites then usually seen in museums.

The display cases are arranged mostly by meteorite family. The Carbonaceous inone and the Differentiated in another. The Chondrites are in another and so forth.There is one case devoted to the meteorites that were donated to the UCLAcollection by Arlene and Ted Schlazer. It is also where visitors will find the wonderfulback-lit displays of several pallasites.

Page 20: Meteorite Times Magazine

Etched Iron Meteorites, Mesosiderites and Pallasites are the main feature of the displaycase containing the donations by Arlene and Ted Schlazer.

I guess it is time to personalize the visit to the gallery. After all I don’t want to show

Page 21: Meteorite Times Magazine

you everything here. There is a case devoted to California meteorites. I have severaltype specimens residing at UCLA in the permanent collection. One of them is aCalifornia find that was classified by Dr. Rubin. It is small and old and unless theycreate a display case devoted to weather beaten and ugly meteorites it will neversee the light of day. But, it is always fun to stand in front of a case containingCalifornia meteorites. Hunting meteorites with my friends especially Paul Harris hasbeen some of the most enjoyable times in the desert of my life. And as I stood infront of the California Meteorites display case I saw one that really caught my eye.The specimen is El Mirage Dry Lake 004. I will always remember the day that Paulfound the first ever meteorite to be recovered on El Mirage. That meteorite is EMDL001 and that little baby was classified at UCLA and a piece of it will reside thereforever.

El Mirage Dry Lake 004 is just one of about 250 meteorites that have been found inCalifornia and UCLA has been an important place for the research and analysis done onthem.

I got a chance to speak with Jason and with Nick and did not feel too by myselfduring the afternoon. By the time I left after seeing all the meteorites and especiallythe California display case I was feeling again like a tiny part of the much biggercommunity of the meteorite world.

Page 22: Meteorite Times Magazine

Just as a final note I loved the impact melt display case. I had a beautiful impact meltclassified about two years ago by Dr. Rubin. That story is in the back issues ofMeteorite Times. It is NWA 7347. No it is not on display either, but a huge slice ofChico is. I thought I had two nice pieces of Chico each with the core hole. But, thepiece at the UCLA Meteorite Gallery is from way deeper in the Chico mass andnumerous times larger than mine. For me nothing beats a really nice impact meltmeteorite.

Impact melt meteorites are a type that record a more violent history in their rock. Chicois a beautiful impact melt that needs to be seen up close so make sure to see it whenyou visit the Gallery.

The Meteorite Gallery at ULCA is open week days except holidays from 9 AM to 4PMand is located on the third floor of the Geology Building in Room 3697. They havecreated a great website about the gallery which can be found athttp://www.meteorites.ucla.edu/gallery/

Meteorite Times MagazineSan Bernardino Wash (L5)by Robert Verish

San Bernardino Wash (L5)An apparent strewn-field in the California Mojave Desert.

High up into the Pinto Mountains there is a surprisingly flat valley that is drained bythe San Bernardino Wash. Ironically, this wash isn’t in San Bernardino County. It islocated just south of the county line in Riverside County. Being located this far southin the mountain range, this wash drains into the Pinto Basin, which forms thenortheastern margin of the Joshua Tree National Park.

This wedge of the mountains, north of the park boundary and south of the countyline forms a dense concentration of mines and claims generally known as the DaleMining District. Located 18 miles southeast of Twentynine Palms, miners weredrawn to the area as early as 1881 by reports of gold in the Pinto Mountains. Duringits heyday, both lode and placer gold mining took place, and saw the birth and deathof two mining camps – now the ghost towns of Old Dale and New Dale. By its peakproduction period in 1898 there were as many as 3,000 miners within this miningdistrict. This intense influx of prospecting activity helped give local feature colorful

Page 25: Meteorite Times Magazine

names, such as Fried Liver Wash and Humbug Mountains. Today, there is stillintense activity, but it only occurs on the weekend when “treasure-seeking” clubstake forays to their prospecting claims.

Typical crowd of prospectors on a modern-day weekend up in the Dale MiningDistrict

Some people consider there to be two mining districts in this area, both of which areseparated by a watershed: the Virginia Dale District to the north, and to the south ofthe watershed (which includes the San Bernardino Wash) is the Pinto Basin MiningDistrict, comprising the Gold Crown, the Goldenrod, the Meek, the Mission, theRusty Gold, and other smaller mines. It is the renewed interest in gold prospectingat these mines that has resulted in the inadvertent recovery of a number of stonymeteorites.

It shouldn’t come as a surprise that meteorites could be found in this area. After all,this is the portion of California meteorite history that was written by LaPaz andNininger, which includes the Dale/Zulu Queen Mine (L3.7) and PintoMtns/Twentynine Palms (L6) meteorites; all found in these mining districts morethan 50 years ago.

That was the previous century. But starting this century, I began to hear rumors ofother meteorites being found in these mining camps by prospectors, but I nevercould get first-hand corroboration. And on those rare occurrences when I wouldactually get to examine someone’s want-to-be “meteorite” specimen, it wouldalways be hematite, or some other meteor-wrong. So, each time my hopes offinding a Zulu Queen Mine or Pinto Mountains strewn-field got dashed, I would bemore and more convinced that all of these rumors were just wishful thinking.

But then, around 2011, something happened. It was an eBay auction! It wasn’tanything special. It just simply stated, “California Meteorite – 35 grams”accompanied by a single image and a “guarantee”. The image was of good enoughquality to get me to contact the Seller, where I confirmed that he was the finder andthat he found it near Gold Crown Road. Well, long-story-short, I wasn’t the only one

Page 26: Meteorite Times Magazine

that he found it near Gold Crown Road. Well, long-story-short, I wasn’t the only onewatching this auction and I was out-bid by my friend and colleague, Jason Utas. Inthe end this wasn’t such a bad thing, because Jason did what I was planning ondoing. He turned-in the specimen to UCLA to be classified and by February 2012,this specimen and several other stones were officially in the Meteoritical Bulletin.They are now collectively known as the San Bernardino Wash (L5) meteorite.

The “write-up” that appeared in the Bulletin for this meteorite was very informative. (Iwish that all entries into the Bulletin had this level of recovery information.) From thatdata, I learned that a number of stones had been recovered, and that several ofthem were found by Fred Mason. I knew Fred. We had hunted together atFranconia, Arizona. So I contacted Fred and asked him if he had any specimens stillavailable. He told me that he had just shared his last available stone with anotherhunting partner. He could tell I was disappointed (his were the last stones available).Because he was unable to give me any leads as to where I could find anotheravailable stone, Fred, the kind gentleman that he is, offered to have me join him athis gold-claim and he would show me where he found his SBW specimens. It was along-shot, but it was my last-chance.

The next time that Fred went to his claim I met him at the Rusty Gold Mine, and heproceeded to give me a tour of where he found his placer gold and of where hefound his meteorites. He suggested that I should focus my metal-detecting searchon a particular outcrop where he had previously found some small fragments. It washis opinion that a stone from this fall had struck this granitic outcrop and hadpulverized into many small pieces. I thanked Fred profusely for pointing me in theright direction, and I quickly took off while rapidly swinging my detector coil.

But a meteorite wasn’t the only thing that struck this outcrop. There were many leadbullets that splattered against these rocks, as well. This outcrop appeard to havebeen used for target-practice. And it seemed like it would take me all day to cleanthis find location of all the artifact iron and lead bullets. But I figured that if there wasthis much man-made material left behind by all of the previous prospectors, thenthere was still a chance that a piece of the meteorite may have been missed.

But by the end of the day, I had not (knowingly) found any meteorites, or gold. All Ihad to show for my efforts was a sandwich bag full of hot-rocks and iron/leadartifacts. But I did get introduced to a couple of Fred’s fellow nugget-shooters.Everyone I met was very keen to talk to me about gold prospecting, but they thoughtit curious that I was more interested in the “meteors” that they were inadvertentlyfinding. Before leaving the Dale Mining District, I gave everyone that I met my cardand expressed my interest in acquiring any of the meteorites that they would bewilling to part with. I told Fred that I was very appreciative of his hospitality and forgiving me permission to search for meteorites on his gold claim, as well as, forintroducing me to his friends and partners. I told him that I look forward to returningand extending my search for meteorites out from the Dale area and into otherportions of the Pinto Mountains.

Now I need to explain what I meant when I wrote, “I had not (knowingly) found anymeteorites”.

Page 27: Meteorite Times Magazine

After I returned home from the hunt, I took the bag of hot-rocks and iron/leadartifacts, washed all the dirt off of them, lined them all up on a board, andphotographed the entire collection before I examine each specimen under amicroscope. That was when I discovered that one of the “pieces of rust” wasactually a fine-pebble-sized chondrite. (You can see what I saw through mymicroscope in the image below.)

(One of these is the meteorite fragment depicted in the image below)

Page 28: Meteorite Times Magazine

San Bernardino Wash (L5) – Riverside County, CA

Luckily, when I first metal-detected this “sandy rust-ball” I didn’t waste time in thefield grinding a window into it, because now I had enough mass to actually saw-off asample to make a thin-section and still have a type-specimen remaining. I went tothe trouble of doing this so that I could get a petrologic microscope examination inorder to attempt a visual-pairing of this find to the Fred Mason find, and hence to theSan Bernardino Wash (L5) type-specimen, which would corroborate Fred’s find andconfirm the existence of this strewn-field. It would also help this effort to acquiremore finds. The positive results obtained from the optical examination prompted meto do just that. Soon, I was making a return trip to the San Bernardino Wash.

The continual gold prospecting with metal detectors has inadvertently resulted in therecovery of additional chondritic stones.

None of these subsequent finds can be considered as whole stones. They are allfragments, and in clusters, suggestive of the falling stones “splattering” uponcontact with the rocky ground. Although in proximity with each other, somefragments appear to be much less weathered than the majority of finds, indicating avery micro-environment controlling the weathering of some fragments. So, in orderto prove that these “less weathered” fragments were not xenolithic to the strewn-field, two specimens were sampled, thin-sectioned, micro-probed, andcharacterized. The results proved that these specimens were paired to SanBernardino Wash (L5)- see images below for comparison.

Page 32: Meteorite Times Magazine

Although there were some variations in weathering grade (W1-W3)and even less inshock stage (S1-S2), all of the SBW fragments found in this study had a commoncharacteristic, that of being friable and of having a porous groundmass. In otherwords, when specimens were cut with a saw blade, the cut surface would showwhere many grains and chondrules had been plucked-away. It was too difficult toattempt to grind and polish a cut surface. This stood in contrast to my PintoMountains specimen which displayed a more recrystallized (less friable)groundmass, and chondrules that were more equilibrated with the matrix. Althoughnot necessarily a part of this study, but for completeness, a sample of my PintoMountains specimen was thin-sectioned and characterized, as well – see tablebelow for comparison.

The image at the top of this article is a view of the Rusty Gold Mine claim, whichis just one of many active claims in the San Bernardino Wash area. All of theseare “placer & hardrock gold claims”, and even though meteorites can’t beincluded in a gold claim (because they are “non-relocateable”)there is no way todistinguish between metal-detecting for meteorites (which is allowed) from metaldetecting for gold (which requires permission from the claim-holder)! This articlein no way suggests prospecting on a claim without permission. For moreinformation, see BLM Land Use Policy.)

Meteorite Times MagazineDhofar 008 L3.3by John Kashuba

In thin section under the microscope it is easy to see that the components of Dhofar008 L3.3 underwent several episodes of processing before their final assembly anddelivery to earth. We see it in layered features and in the presence of envelopingcompound chondrules.

Enveloping compound chondrules have one or more chondrules completelyenclosed in another.With enveloping compound chondrules the enclosed chondrules obviously had toform before the chondrule into which it became incorporated.

In another class of compound chondrules adhering chondrules became attachedwhen molten or still-plastic chondrules impacted and stuck to already solidchondrules.

Sibling Compound Chondrules are adhering chondrules with similar textures andcompositions.

Independent Compound Chondrules are adhering chondrules with different texturesand compositions.

Returning to enveloping chondrules, if the interior and the enclosing chondrules areof the same type it can be difficult to discern the existence of the compoundsituation. Fortunately here we have barred olivine (BO) chondrules in porphyriticolivine pyroxene (POP) chondrules. The textural differences stand out. Further, BOchondrules are often single skeletal crystals that go to optical extinction all at once.This, too, highlights their presence in POP chondrules when the polarizing filters arerotated.

Meteorite Times MagazineAn Aussie Flanged Button Too Good to be True!by Norm Lehrman

About 10 years ago I was approached by a guy that had just inherited a tektitecollection that he wanted to liquidate. Included were about 20 Australite flangedbuttons. Working from a photo, I selected about half of them and we made a deal.When they arrived I was astounded. They were better than any I had ever seenbefore. I realized that I had not paid anywhere near enough for them, and Iimmediately began to compose an email to the seller offering to double what I hadpaid. I found myself writing that they were just too good to be true—

As those loaded words scrolled across my cerebral cortex, alarms startedsounding. After a career of evaluating mining properties, I had encountered “toogood to be true” enough times to know to pay attention. I picked up a knife to test thehardness of one of the buttons. It was plastic!

Page 50: Meteorite Times Magazine

This led directly to some radical changes in my email wording! As it turned out, thiswas not a case of fraudulent misrepresentation. The seller, who was not at allknowledgeable about tektites, was mortified and wanted to make things right. Goingback to the photos that he had originally supplied, I could see that most of those thatI had not selected had obvious imperfections—chips, sand and dirt in the recesses,and less than perfect form. We adjusted the deal to obtain those, and they all provedto be real, and well worth the money.

On further investigation, we learned that the deceased party had been a curator atthe Smithsonian. Apparently they had obtained quality casts of some of the finestflanged buttons ever found. I returned all but one to the seller. The picturesaccompanying this article are of that superb piece. Somewhere, probably in a majormuseum collection, the original specimen is out there. (Let me know if yourecognize it.)

This quality cast has proven to be a useful part of our collection. It illustrates all ofthe best features of a world-class flanged button and I can pass it around a room fullof kids without fear— Whenever I show it, I tell this story and use it to reinforce thatimmensely great life lesson, that applies to tektites, emeralds, human beings andmost everything else on earth: “If it looks too good to be true, it probably is!”

Meteorite Times MagazineLEEDEY Meteoriteby Anne Black

The Leedey meteorite fell in the evening of November 25, 1943 in westernOklahoma. The story of its recovery tells marvelously well how the travelingconditions and the communications have changed in the last 70 years. It is also amarvelous example of collaboration between the two best known meteorites huntersof the time: Oscar Monnig and Harvey Nininger. And no one can tell it better thanOscar Monnig himself.

This report has apparently never been published and has been in Dr. Elhmann’sprivate records all these years. So I will let him introduce it:

The Leedey meteorite was thus recovered quickly but then it had to wait. Was it dueto pre-occupation with World War Two or could it be that Mr. Monnig was too busymanaging the family stores, we don’t know. The meteorite was quickly described inthe 1950s by Nininger but it was not analyzed until the 1970s and was finallypublished in the Meteoritical Bulletin in 1997, with this map of the strewn field.

Page 53: Meteorite Times Magazine

Map published in Meteoritics & Planetary Sciences, 1997

Page 56: Meteorite Times Magazine

This picture was also in Dr. Ehlmann’s papers and it does show the main mass ofthe Leedey meteorite, however there is no note as to who the car belonged to. Couldit be the car that Harvey Nininger was driving when he went to pick up Mr. Monnig?

Page 57: Meteorite Times Magazine

As per their prior agreement to divide anything they would find equally between thetwo of them, Oscar Monnig and Harvey Nininger split the main mass of 20.4 kilosright down the middle, half of it is now proudly displayed in Monnig Meteorite Gallery,in the Texas Christian University in Fort Worth. The other half was acquired byArizona State University along with most of Nininger’s meteorite collection in 1961.
