From the outside it looks like Thunderstorm Jasper, but the inside is'nt quite right, the pattern is different. It is curved rather than the classic lightening bolts. Did you notice any tiny gold looking metal flakes in the cut end ? Now that I think about it, I remember seeing some Thunderstorm that DID have orbs in it.Could possibly be thats what you have there. Some nodules are blade eaters of the higest order !

No, there are no metal flakes at all in this material. It "feel" different than all of the other jaspers I picked up that day. Its hard to describe but the outside of the material feels almost chalky and not slippery at all like most rocks. When I cut the end, it was not a clean cut. I ended up taking a hammer to it to get that end piece off. When I hit it with a hammer, one part of it had a peeled look rather than a broke off look. You know, like when you peel the bark of a tree and some of the inside peels off with it. But this material is definitely a rock, and its hard.

Petrified wood varies from place to place, and I'm completely green on the wood in Oregon. That said, I would not call your find petrified wood. Although it has some resemblance to petwood on the outside, on the inside it appears nothing like petwood, at least nothing like the petwood I find. There are a bunch of petwood look-alikes, and I think this is one of them.

As Don said, it looks organic on the outside, but the inside does not. But then a lot of the western wood doesn't even come close to resembling wood.
Where art thou Mel? You're needed here.

Hmmm, I guess I have a mystery on my hands. "Mel, hey MEL!!! help me please!!!"
Ok, here is another weird thing to add about this rock "thing". Although there are no metallic flakes, the reddish/brown portions on the outside almost had a weird chatoyance about them. When I collected it and got it wet, it had a weird little shimmer to it. in spots. I think chatoyance is overstating it but that was my first thought when I looked at it in the sun. But it can only be seen in very bright light. Weird.

OK, I'm thinking not wood but rather a type of serpentine. The shimmer you've mentioned coupled with the layered look which peels sounds like the sort of cleavage you'd expect in that material as does the brown exterior with the funny feel to it and the greenish interior. Can you scratch the cut face with a hard steel blade or nail? Serpentine should scratch but a jasper or jade like material will not. If it doesn't scratch, probably a jasper or chert of some sort.....Mel

Mel,
It DOES scratch with a steel knife. Thank you so much for the info! There is a lot of Serpentine in California isnt there? The weird chalky exterior and shimmer plus how it peeled really threw me off.

Shannon: Yes, serpentine rocks are about one of the commonest metamorphic rock types in California. Some of them are very nice gemstones too often resembling good jade. Birdseye serpentine is a personal favorite with me. All kinds all over parts of Oregon and Washington too....Mel

After all the descriptions, I was going to ask if it could be some form of serpentine? It's way cool, as are the figurines. Learning more, every time I log on. How fun!
