I'd agree with jadedvision. The fractures plus the zoned color on the plumes make me think of Canadian River Plume too. Years ago at Quartzite a rancher brought in a whole trailer load of plume from his pastures. Big pieces and fractured but the plume did seem to occur in zones or broad bands, reds, pinks, yellows , even blacks in zones in some of the boulders. Can't think of another plume I've seen that does that.

Beautiful stuff. Unfortunately, I have no clue what it is.

I thought Canadian River plume, too.
Guess I'll be the one that asks... Can a jasper be plumey? I thought that was only agate.

I’m glad someone asked because I was wondering the same thing!

Nice one beefjello . My first impression was Canadian River too. I thought Canadian River plume, too. Guess I'll be the one that asks... Can a jasper be plumey? I thought that was only agate.
Do you recall this plumey jasper that I posted a couple of months ago. Folks here on the Oregon Coast call it Flower Jasper. What do you think Sabre52 ?

Amygdule, *L* Good question. I suppose technically, jasper is opaque, agate translucent, jasp/agate a mix so most all "plume agates" are jasper/agate as they are part translucent, part opaque. I'd call your flower jasper plume agate though, as it is so like other so called plume agates. Yours really reminds me of Bloody Basin and Tonto Plume agate from AZ. Now there is a fine plume jasper that I mined a lot of in the North Cady Mtns of California. Golden plumes on an opaque red jasper. Zero translucency. Unfortunately, I have only a couple of rather plain slabs left and sold the rest. Here are a couple examples. Has some agate veining but very opaque still, more on the plume agate end of the scale. The plume jasper from the same location had the gold on red jasper plumes you see in these slabs but large one to two inch plumes against the opaque red.

Except for the color it looks like some South Texas plume agates

Thank you for the explanation Sabre52 Another example of the ocean tumbled nuggets that I find on the beach. Sorry for the threadjack beefjello :)

Wow those plume cobbles are excellent and obviously "of a type". From the smoothness they've traveled and been rolled a good long while. Do you now of an situ location for the plume deposit they traveled from? I'm going to have to go into my agate notebooks and see if I can figure that out. I love a good mystery.
Research done. Looks like a dead ringer for Willamette River Plume agate. Close to Bear Creek Plume from Prineville too but considering the Willamette dumps a lot of agate onto the ocean, I'll go with that one *L*. Oops, answered my own question, Bear Creek empties into the Willamette Valley hince could be the same agate source.

Thaaaaatt’s what it is.. Sabre52 @jadedvision thanks for the ID’s guys! rockjunquie I cut one of the slabs very thin, like 1 ½ mm or so. Held it up to the sun and saw little or no translucency. That’s why I referred to this as ‘jasper’ amygdule no need to worry about thread jacking.. especially with beauties like that Have a great evening everyone!

Cut that thin, if it was agate- you'd know it. So, jasper it is. Learn something new everyday.

Sabre52I have never found a source for the plume There is the Siletz and Yachats Basalt between here and the Willamette Valley It's hard to tell where all these different types of rocks come from. Alluvium

Amygdule, Yep sourcing beach rock is difficult due to the fact that longshore drift can deposit rock far from a river mouth. I used to hound the Ventura beaches in Califoria and I'd find Stone Canyon type jasper cobbles far from the creeks draining the Stone Canyon deposits. That being said, the plume in your pebbles is a dead ringer for Willamette or Bear Creek plume agate.
