A Boeing Bomb???

Concrete over pour?

dinosaur dropping

Is it really heavy?

[chevota78]

yes it is really heavy, but not magnetic, it was found out in the middle of nowhere I don't think it is concrete, close up it looks like a bunch of big rocks fused together by something. Maybe lava?

[Burchoid]

Looks like really old cement with rocks in it to me. Is that piece of wood stuck in it? If so, its a fence post.

[rushing]

Reminds of of what Joe found in the movie Joe Dirt.

[chevota78]

no it's sitting on a piece of wood right by the cabin.

[Urbanflyguy]

send the pic to the UofM geology dept i bet they can tell you, but it looks like some sort of sedimentry sort of rock

[leech~~]

It looks like a very rough footing pure of rocks a cement!

[chevota78]

i broke off some samples to send in sometime. Is there a link i can get the email address at

[bobbymalone]

+3 or +4 or whatever we are up to now for concrete aggregate.

[tweedlap]

I'd like a closer look. There is a small formation that is formed from lightning hitting the ground too....I forget what they call them.

gold???

Petrified rock.

I think Dark has a point, the substance he mentioned is called a Fulgurite:

And come to speak of it, that stone does have an uncanny semblance to a Fulgurite, although it would take a serious piece of metal like a Weathervane to cause just such a rock agglutination. Since Fulgurite's have a similarity to Obsidian, due to them being like a tempered natural glass; if you tap a (Flint Knapping) Billet (or Aluminum pipe) against it.. does it have a higher pitch? If so it could be a Fulgurite: Natural Glass and Cryptocrystalline specimens are more sonic in the sounds they emit when struck versus you're average country stone. I own a Fulgurite, and another way you can tell if you're specimen is one, is due to it being as friable as a clod of sand; if it's too heavy it likely is not one... since Fulgurites are like Aerogel in their lightness. The only other possibility of it being in the Fulgurite ballpark, is that it is a lighting zapped stone called a "Rock Fulgurite": which is a native stone that is struck by lighting and contains the glassy vugs caused by the lighting.

Hope this helps.

Thank you for the link i sent a pic in an email.

I do not think it was concrete based on where i am told it was found and there were two other pieces this was the largest one.

[chevota78]

It was found before the 60's

I'm still going with concrete over pour.

Let's say a 6000 pound, 3/4 minus, 6&1/2 to 7 bag mix with some fly ash and gray tint. This was a common driveway recipe we used the late 1960's minus the gray tint.

When I last checked, sometime in the early 90's there were over 800 different recipe's/combination's of concrete mixes.
