Well, isn't that just the coolest thing!JimR said:
You know I don't have a GPS, but I know the excite spot I found them so I could use goggle maps to get the mapped locations.
They say testing is free, but there is a $15.00 shipping and handling charge. But they also say if the sample you send in isn't real then they will return a real meteorite to you! I'm thinking I might just send them in and see one they say.
Thanks for the replies and the link!

Both Mark and Jim`s photos look like possible meteorites, but testing by someone that can tell the difference between a rock and a meteorite would answer any doubt. Literally tons of stuff fall on the earth each day. Most of the earth is water so we lose those. The rest fall on land. Rocky areas tend to keep them near the surface. Meteorites I think, travel at about 20,000 40,000 miles an hour, so when they hit soil they can go quite deep making them harder to find. Near the north pole they ride around on snowmobiles and pick them up on the surface. They tend to stand out on the white snow and ice. I would like to find one.
Hi, Bob:
My meteorites were authenticated by the late Dr. Jim Kriegh, the discover of the Gold Basin meteorite strewn field. You're right that they do enter the atmosphere at a very high rate of speed, but unless they're huge most reach the surface at around 100-200 mph. Some penetrate the ground a ways but many can be found right on the surface. Up in Wisconsin where you live you may be able to find ancient ones (especially irons) in moraines where the glaciers pushed them down from Canada during the last ice age.

I was reading a little about meteorites on the Net and one thing they have to help identify them are what he called "Stress Cracks".
So as small as the ones I have I thought they should still have these cracks in them!
I took the bigger one and cleaned it up a bit and took another picture.

Wow, Mark. I hope you have sent a piece to the lab I mentioned because I'm thinking you may have something there. Many of my Gold Basin meteorites have the same type of cracks. I think most of them are caused by weathering (freezing and thawing and moisture entering the stones). I just sent a few small pieces of iron I found last year to have them tested. I tested them for nickel myself and they came out positive, which is a good sign. A local place wanted to charge a small fortune to analyze them but the New England Meteoritical Service is a great deal at $15.00.
