  1. Bob, check out the Bob's Findings article titled Lost Lake in meteorite times. He found some more "fragile crust, friable matrix" :grin: Mike in CO
  2. Hi Chazeman2, Even in a city you might be able to find some small stones using strong magnets. See if you can find out what the municipality does with the sweepings that come off the street. If you can get permission, go run a strong magnet over the pile(s) of stuff the sweeper units dump out. Be prepared, you will also get a lot of unwanted metal objects on the magnet. Wear gloves to clean the magnets off. Another thing to look for is places where the small gravels from the blacktop gets washed into piles. Drag the magnet through there. You never know, you just might pick something up
  3. I'll never tire of your posts. Good one! Mike in CO
  4. Hi Cam, Sounds like you might be from central part of the state. I'm over in southwestern part. Glad to hear you are getting an opportunity to try your machine in AZ. I'm hoping to do that sometime soon myself. Best of luck on your trip. Hope you find a big meteorite or many small ones. Gold nuggets would be great too. Mike in CO
  5. Fantastic! Now that's a find. Maybe another ataxite? Probably on it's way to the Smithsonian NMNH. Wherever it ends up, I hope someone shares some more pictures of it cleaned up. Nice find! Mike in CO Sorry, need to edit that. I see you are in Brazil. Make that read Brazil's Museum of Earth Sciences instead of the Smithsonian NMNH.
  6. Hej, Have you contacted the Risoe? Or, the University of Copenhagen, Natural History Museum of Denmark (Henning Haack is the Curator according to the website) Show us a picture (viser os et billede Mike
  7. I would try to run the coil over some known meteorite samples to see how the machine reacts. That way when out in the field hunting, you have a better idea of what indications to watch for. Just my 2 cents. Mike in CO
  8. My whole thing started one day metal detecting in a graveled parking area at one of my friends property. I thought I had picked up a signal from a coin. I started digging and didn't come up with the coin. I started going thru the gravel I had moved around and discovered a small heavy object. The gravel was muddy and the best I could see at the time was that I had something about the size of a half dollar but it was very heavy. I had to go meet my BIL at the church in a few minutes, so I loaded up in the truck and headed over there. When I got out of the truck there at the church, there w
  9. I know my use of the word micro is not exactly correct but at least to me it is in this respect... My specimens are small enough that in order to see the detail properly requires magnification. Not just 10x but in some cases 30 to 70x. Microscope - micro, hopefully you can see my connection. I contacted a lady at Cascadia today. She was very kind to respond right away but she suggested I try U of A first. I will do that next. The saga continues. I'm amazed at how difficult it can be to get certification of small specimens. In meteorites, size matters, eh? thanks for the response.
  10. Yes I believe some time back I exchanged emails with him. I wanted to let him know I thought his article was very good. Anyway, yes he does hunt micro size but when he says micro he means very small. When I say I am hunting micros, I mean sizes like less than 1/2" . I know, not the true meaning of the word. Mike
  11. Pardon me for resurrecting this older thread but I have an update on what I had posted before. I finally had Dr. Wasson at UCLA respond to one of my emails. He first suggested I send a sample of my suspect irons. But when I made a point to tell him how small they are, he gave me the we're too busy reply. I certainly understand him saying that. I would imagine they are too busy for small stuff like I have. I'm not disappointed but am feeling a bit challenged now to find someone else (with credentials) that will take a look at a couple of the pieces I have. If I am correct in my evaluat
  12. You should do well with the 6.5" elliptical coil or 10". Mine will pick up a BB at 8" depth. It has the 10" ellliptical. I once found a hairpin at close to 10" depth. Trick is of course to know what to listen for. It is all in the tones with the Gold Bug. Probably just as important as the coil is to get a good set of earphones. I swung a piece of Allende under the coil. To me, it sounded different than the normal hot rock. I may not have realized that were it not that I had spent quite a few hours swinging it before that. Anyhow, the Gold Bug seems to be a good detector for the pric
  13. Hey Jim, and others, I still have not had any reply from UCLA on my request to have a stone looked at. I even tried to contact one of the dealers here in CO and no reply, so... Maybe I will send a piece of one of my little collection pieces to the folks there at ASU to see if they would take a look. Only thing is, reading through the instructions on that page, it says you should send something about 1" in size. Heck, none of my little pieces are over 1/4". : ) Maybe they will still take a look. Thanks for posting that link Jim. It may be just what the doctor ordered for me too. Mike
  14. Hi Bob, There is always the "streak test" you could do to determine what that black stuff is. If hematite, red; if magnetite, dark gray, and so on. If stony meteorite with glassy crust, none basically. Good luck with your hunting. Mike in CO
