We have two of these rocks and I saw a internet post saying this is Agate Jasper and listed this description. Description of Physical Characteristics: Color: Agate Jasper is a when both agate and jasper form together. The color ranges from yellow to brown or green. Part if the material will be banded and be translucent while the remaining material will be mottled and opaque. Texture: Fine grain Luster: Vitreous Distribution Comments: Agate Jasper is associated with the Pacific Northwest and Great Basin. It is most notable in Oregon and northern California Here are our pics.       |

Both amazing, but that one on the left is fascinating! Out of curiosity, what're your plans for that one? Tumble?

I was thinking tumble but the voids worry me, I saw a post where a guy filled voids with glue first but I don't know what type or if would work on this one.

Very nice! I'm guessing it's from the Stony Creek/Black Butte lake area?

Nope I have never heard of the Stony Creek/Black Butte lake area, where is that at. These came from the Clarks Fork River in Montana

Nice finds!
Very similar to some pretty common stuff at a couple of my favorite sites in NV. Some of my favorite material. Yellow with clear/white agate, often banded, is the most common, but colors range into red/purple and less commonly green.
There seem to be two distinct varieties which occur in close proximity or even in the same stones. Mossy features with short plumes and breccia with broken jasper filled by agate both can be found. My uneducated presumption has always been that the mossy is from simultaneous or near-simultaneous (on a geological scale) formation, and the brecciated features come from jasper that has been broken up and "rewelded" by bathing in silica soup.

I read what little I could find on this stuff and it is diffidently more common on the west coast/ great basin area then here. I know it has been found on the Yellowstone river here and I think I picked up one of mine on the Clarks Fork river but I'm not sure. I need to start keeping better track of that.

Like this?   This from the Southern California desert north of the town of Ocotillo. So many rocks out there that have voids or cracks infilled. |
