I rolled it in the car again and took it to the planetarium in bay city. The astronomer there, Mike Murray, said he thought it looked very promising. I'm waiting to hear back from him.

Almost 2 years later and still no answers. I was just looking at the first part of this thread. Definitely an interesting specimen. Thanks for keeping us informed of the progress.

Well it's been more like twelve years since I first meandered onto this journey. I put it on the back burner awhile until I get a new idea. Then it's off to the races! Thank you all for contributing and paying attention to this thread. I don't expect to hear from the curator until after the B holidays but I will let you all know what he said.

Well, I didn't get anywhere down that road either. I've been seriously considering cutting it open. My own curiosity of the interior is becoming more important than anything else at this point.

Very interesting mystery.

I myself have been very disappointed in the world of geologists when trying to identify a rock specimen. I laughed when you said where you are NOT going to send your kids to college. Geology education might be pretty poor. I'm going to be taking a geology class next semester. It will probably be pretty basic stuff but I love learning earth sciences when I have the opportunity.

I was going to suggest the field museum or other museums but as I read the thread you have already done that. It certainly looks like one to me. I think the comment about slag not being as dense/heavy is correct but I am by far from an expert.

It does seem like people just don't find this topic that interesting sadly. There was a show on TV a few years ago I recall being something like "meteorite hunters". Too bad you couldn't ring them up and get them to visit you for an episode.

My guess is being something that big would have made a pretty large crater and be much older than a house. Thousands of years older. To think about if it is mill slag or not I'd look into the history of where you live and proximity to historic steel factories. I bet you already thought about that in depth too.

I'd hate to see you cut it. The ones I have seen in museums I was always sad when they did things like cut them or drill bolts into them to anchor down as if they were so common it's not a big deal. The naturist in me likes to see things left undisturbed or unmodified. I totally understand your curiosity too and drilling a core sample in one of the holes is interesting. A core sample would require a really special bit though I imagine.

I wonder what kind of isotope tests could be performed on it.

Clarification: I am sending my kids to college, just not that particular one. My oldest starts in the fall, he secured a full ride scholarship and plans to be a nuclear engineer. I'm very proud.

We tried the meteorite men at one point, they were not receptive. I'd have to check my records to remember exactly what was said.

There were no steel mills near the site of the find. Not that I found anyway.

I'm quite happy to have a post here and encourage all to do so. I think this topic is interesting to a broad spectrum of people, but also information is limited even amongst professionals in the field. I was thinking that I need to find a specialist in the rare meteorites.

The recent fellow at the Bay City Planetarium said it couldn't be one because of the absence of fusion crust. My thought on this is that it has been outside exposed to the weather and has probably deteriorated. My research tells me this is common.

If nothing else you are expanding your knowledge of geology, astronomy and research and it appears you enjoy it. That is ALWAYS a good thing. Just as long as you never stress about it, obsess over it, or make it all about money. I do wish you luck in finding that top dollar buyer though. :)

I have learned a lot on this subject in the past few years. This is a very interesting subject to me. My ultimate goal would be to get it to auction, but I'm a long way from that. My theory (based mostly on rough math and more theory lol) is that the interior differs from what's on the outside. My curiosity is piqued around this part of the subject at present. My thought was to get a sample of what's inside, if it does differ from the rest of it, and have that tested somewhere. I keep trying different routes on testing mostly because I'm out of ideas on experiments that I can perform myself. Any and all thoughts are greatly appreciated.

I tried cutting into it. A sawzall did not work. It just ruined a new cobalt blade. This was not a failure, it just yielded results. Next I tried a chop saw blade on a hand grinder. It cut right through the rocky exterior. About 3 or 4 hundred thousandths in I hit metal. This confirms my hypothesis that the interior and exterior are different materials. I used a blade I got from work that we use to cut stainless steel. These blades rip through stainless at a pretty good rate. It cut the rocky exterior at a similar pace. However when I got through to the metal, my progress ceased. I was just watching the blade get smaller, and it didn't take long to use the whole thing up without making more progress. Whatever is in there is harder than hell. My conclusion is that I'm not going to be able to cut this with mere hand tools.

We have a local shop that has a laser cutter. Maybe call around to your local metal fabricating shops. They may have an industrial cutter, or some ideas on what you're dealing with.

Yes I have heard of that. We have a water jet at my work but it is to small by but a few inches. It cuts with 96,000 psi water mixed with garnet. The water jet and a laser cutter seem like good options because of the lack of a cutting blade. We contacted a headstone cutting place but they wouldn't give us the time of day. Just as well, though, I would hate to ruin a blade like that and even worse have to pay for it. These other two seem like better options.

Tile saw might do it. Sounds like a magnetite-hematite concretion, with enough magnetite to keep it from streaking red but not so much that it's strongly magnetic. Mineral mixtures can precipitate in funny ways such that they appear mysterious and meteoritic. This per the geologist in my family. He says the specific gravity will be pretty high, as you described.

Hematite will streak red or brown. Magnetite will streak black. Most meteorites won't streak at all.

My specimen does not leave a streak. Also it has many regmaglyphs or thumbprints commonly associated with meteorites. This is also not found in magnetite.

Thank you for contributing.

Well, this was from a budding geologist not a veteran, so take with grain of halite. His point that I omitted was that concretions may differ in presentation from their component minerals. Some can also have stuff alloyed in that raises their Moh high enough that they don't streak. I do hope you can cut into the interior and learn something.

Have you considered drilling vs. cutting? Some fancy bits are affordable and you would have a resulting powder with quite tiny pieces that could be examined microscopically, as well as in test solvents. If this was covered in the thread already, sorry for the redundancy.

Yes I have considered boring a hole in it, but a cross section would be much cooler visually. I thought about drilling at the bottom of one the holes.

May be a Quickie-saw with a diamond cutter disc? You might be able to rent one, or find someone using one.

I wondered if that was Canadian for rotary saw, like a Dremel.

I think it is short for quick cut off saw, maybe even a brand, but mostly it is the blade mounted on a gas chain saw type, electric grinder type, among other types, but mostly used for concrete cutting. THE VIDEO IS THE TYPE i WAS THINKING WOULD WORK BEST FOR THIS SITUATION. Sorry about the cap lock. Talking to a concrete shop might spare a few minutes to try cutting for you, if you can find a guy interested in what you have. If not, you may not get the time of day.

Yes, I have considered using a saw like that they use for cutting the gaps in new concrete. Haven't decided on it yet, but I thought it may work. I want to get at a piece of the metal interior and have that tested. This is my thought process at present anyway.

The man who owns this piece had a house fire. Basically the house burned down around it. It has suffered some cracking and a few pieces fell off but all in all has survived intact. What has fallen off is still only the outer two inches, alas I am no closer to getting a glimpse of the middle. If it didn't have fusion crust before, it sure does now hahaha.

wow, I am sorry to hear about the house fire loss! That thing sure does have a history.

Any way to claim it's damage on the insurance policy ;)

It sure does have history. Until it is verified and classified it is just a rock and therefore worth nothing. If we were to try to sell it without documentation we couldn't even advertise it as a meteorite without the possibility of it coming back on me. This is another tale in the story tho.

I took a piece of it and fashioned a stone axe from it. It was very difficult to work with, I ended up using a punch from a press. I presented this to my friend whose house burnt. He was very pleased. This is not really breaking news but I felt it was worth sharing.

There is not really much to add. I did get shot down one more time since I've posted last, but I didn't bother to put any of the information on here. My friend has been after me to break it open and see what's inside, but I'm not ready to do that yet, for a multitude of reasons. I am thinking heavily about paying for a chemical analysis. The money is not really an object, but I still need someone to interpret the data. But at least I would have the data. On an unrelated note, we had a confirmed meteor fall near Ann arbor a few months ago.

Hmm. If it is a meteor, there is a good chance it incorporates potentially quite a lot if Iridium. This hard-wearing metal often turns up at meteor crash-sites. I don't believe it occurs naturally on world, and has to come from elsewhere. If it contains Iridium, it could be a quite valuable indicator to help discover its history.

I'd love to see you get it officially tested. I have been following this thread for years now. Maybe you could start a gofundme just to come up with the money to get it tested at a reputable official place? There might be people out there that would fund something like that just to make sure it's done properly without harming it.

I can get a complete chemical analysis from an electron microscope for around 2 or 3 hundred dollars, which would be easy for me to afford. What they told me on the phone was I would receive a readout saying 5% nickel, 8.8% carbon etc, etc. I haven't done it yet because that information wouldn't tell me a whole lot. I would someone to interpret the data for me, but this would also give me a new area to research. I have been considering it.
