December 17, 2019

Dear collectors,

I am back from my Costa Rica trip. It was overall an enjoyable trip, though often quite warm and sticky (I am not used to humidity, even at relatively cooler temperatures). Kevin’s side of the country was, for the most part, sunny and dry. The dry season, with its strong winds out of the east, was setting in (we did still get some time of sitting in the clouds and watching fog drift by thing – a very, very rare thing for me to see in my part of Colorado but common where he is perched up on the top of a mountain). However, I feared that this might mean that the other side of the mountains might be rainy. I figured the clouds carrying moisture from the Gulf of Mexico to the east might end up getting the moisture wrung out of them as they got stuck against the easterly mountainsides and made their way up and over. Yep, this is indeed what we found. Aguas Zarcas was heavy cloud cover, lots of rain, some (generally minor) wind and at times surprisingly chilly for a tropical area. All of this certainly meant that we weren’t going to be out stomping around looking for specimens on our own (also because it was a bad time for lots of really dangerous snakes in the area. Unlike the ”nope ropes and danger noodles” crawling around my area theirs don’t make any noise to let you know you are getting to close. I have indeed managed to avoid getting bit by a rattle snake hidden in the leaves on a trail a couple times by knowing what they sound like - and that sound ain’t like they present it in the movies folks). So, we had to limit ourselves to meteorites that locals had already found. Unfortunately, it seems that not much is being found any more. Some of the few pieces that were recovered recently are certainly showing their age (I hand picked and avoided those, paying a higher price to do so of coarse) and other pieces (that looked to have been recovered quite earlier) seem to have become special family heirlooms (“not for sale”). Oh well, at least I tried. The few things I did pick up are listed here below at a price only a little lower than I have offered similar pieces in the past (but then, I didn’t really pay much less at the site and am not even including the travel expenses as part of these piece’s direct cost at this point). I am having trouble deciding what piece(s) I want to keep for myself so I thought I’d let fate decide – I’ll keep whatever is the nicest piece listed below that does not sell from this offering.

The other items on this list are the last of the Riker mounted display pieces I picked up as a collection during the Denver Show. All of these have labels and it turns out that one more of these is also a Casper labeled piece that had that label hidden under another different one. I’ll make notes in the descriptions below of what labels come with each specimen.

NOTE: As with the last offering, shipping on most of these (everything but the Aguas Zarcas) is going to be a bit higher (around $5 or $6 for a single item for basic US) as these, being in glass fronted display boxes, will have to be shipped packed in boxes. My usual jewelry boxes in a padded envelope won’t work for most of these pieces.

AGUAS ZARCAS, Costa Rica: Carbonaceous chondrite (CM2). Fell April 23, 2019.. These purchased Dec 9th, 2019.
These are the pieces that, as mentioned above, I bought on the trip I just got back from. These are all natural fragments (though the largest has some claim to being a complete individual) and, after a light cleaning on my part, are quite fresh. Each has at least some fusion crust present (actually, all but the smallest have quite substantial amounts of crust). As mentioned above, the largest piece looks like it could be considered a complete individual. It has around 45% nice thick primary crust coverage with the remainder being angular “broken” surfaces. However, careful inspection shows non-sharp (micro roll-over) edges on the primary crust where it meats one of these “breaks”. Also, a hand lens shows obvious (but small) patches of thicker fusion crust on the high spots of most of these broken surfaces (so they can’t be “after the fall” breaks). One surface looks to be crusted so thin that it looks almost like a smoke coating. There is some hints of smoothing of the break as well as the fact that no real inside texture/ structure can be seen (aside from a couple larger chondrules poking through perhaps) whereas the other fragments (clearly showing post fall breaks) the interior structure is clearly visible. Regardless, I am not pricing this piece higher because of any of this.
1) Natural fragments. All have some crust:
a) 4.4 gram fragment – 16mm x 15mm x 15mm - $350 – about 15% crust covered.
b) 5.0 gram fragment – 20mm x 20mm x 10mm - $400 – about 45% crusted.
c) 7.4 gram fragment – 25mm x 18mm x 12mm - $590 – about 50% crusted.
d) 22.2 gram fragment/ individual – 32mm x 28mm x 20mm - $1700

BRENHAM, Kansas: Stony-iron (Pallasite). Found 1882.
This is a Riker display that has two part slices – one 3.4g (17mm x 12mm x 5mm) and the other 13.5g (25mm x 20mm x 9mm). This has two labels; one (unnamed) that has the two weights as 3.4g and 14.2g. The label that was hidden underneath was a Casper label (for the 3.4g piece) that has “Happy Holidays!” written in the ‘Remarks” line. The larger piece looks to have a Nininger number on it. It certainly has the exact look of a Nininger number paint job, starts with the proper “10” for a Nininger Brenham but the next number/ letter is damaged enough to make it unclear exactly what was painted here (the last 3 look to be 119 though this could be “10M19”). This piece is also the typical thickness that Nininger would have cut back then.
2 part slices – 3.4g and 13.5g (possible Nininger piece) in Riker - $100

CAPE YORK, Greenland: Iron. Medium octahedrite (IIIAB). Found 1818.
Now this is a neat little Riker display. It has a label identifying the Meteorite (name, type, etc.) with “1 GM” handwritten on it, a nice etched 15mm x 10mm thin slice of the meteorite in a gemstone holder and a commemorative Greenland postage stamp (that looks to be from 1978). The stamp seems to show what looks like might be an ancient knife/ tool of some sort (this is indeed what the locals used these meteorites for) on a background of a large etched slice. I am assuming the “1GM” is the rough weight of the slice, but I didn’t pull all of this apart to find out.
15mm x 10mm etched slice, stamp and label in Riker box - $90

ESTHERVILLE, Iowa: Stony-iron (Mesosiderite). Fell May 10, 1879. Tkw = about 320kg.
This is a thick part slice that has its larger portion being the silicate material (though there are still substantial chunks of iron, they show a bit better on the backside). This comes with a metal “meteoritelabels.com” label with the proper 4.75GM weight written in pencil in the specimen weight space.
4.75 gram part slice – 20mm x 13mm x 6mm - $90

HOLBROOK, Arizona: Ordinary chondrite. (L/LL6). Fell July 19, 1912.
Here are two nice complete fresh individuals in a Riker display. These come with a Schooler’s label that has the pair weight of 1.6grams. Yep, this is exactly what my scale got. The smaller piece weighed .68g on my scale and the larger was .92g. The larger piece has some areas of secondary crust (of the type and thickness that leaves no doubt that it is secondary crust, unlike some of the areas on the largest Aguas Zarcas listed above) but is NOT broken and is certainly a complete individual (the smaller piece is pretty much completely covered in primary crust).
2 complete individuals .68g, .92g in Riker with Schooler label -$40

MILLBILLILLIE, Australia: HED achondrite (Eucrite). Fell 1960/ found 1970.
This is a part slice of the more unusual fine-grained textured area of this meteorite (the vast majority of Millbillillie showed a brighter black and white salt and pepper texture). This piece has one natural edge that shows some weathered fusion crust that has some of the orange spots/ staining that shows that this really is a Millbillillie. This has a nice label with it but this does not say who’s label (Ann E. Nonimus??) it was. This label has the weight as 2.4 grams but my scale showed this as 2.2 grams.
2.2 gram part slice – 22mm x 10mm x 3mm - $30

NORTON COUNTY, Kansas: Enstatite achndrite (Aubrite). Fell February 18, 1948.
This is a Riker containing two small fragments of this meteorite along with a Schooler’s label. The label has these as .8g together and this is indeed what my scale showed. Each of these fragments is roughly 10mm x 5mm in size.
2 fragments totaling .8g in Riker with Schooler’s label - $25
