Hello everyone. Several years ago, I purchased this piece and had it polished. I can make an assumption that it was from the South Bay Area of Santa Clara County. California. Now I know these poppy jaspers are region specific, so i'm rather curious of its origin. Is it most likely from 1)Coyote Creek, 2)Guadalupe Reservoir, or 3)Morgan Hill? Sorry for the blurry pictures (oops). Thanks! Henry

I'd guess Morgan Hill, but Sabre52 is the real poppy expert.

To me it looks like Llagas creek, Morgan Hill material. I've got to admit though that, since Coyote Creek is a different drainage, I don't really remember having seen any poppy specifically from Coyote Creek. I've only seen good looking Stone Canyon like brecciated jasper from there....Mel

Thank you Sabre52! Ah, so the Llagas Creek material is still classified under "Morgan Hill Poppy Jasper"...as a sub-category.

Henry, So far as I know, Morgan Hill is just used as a general category for poppy jasper found in the Llagas Creek and Uvas Creek drainages. Several sites and claims have been found over the years and all on private property. Guadalupe Poppy came from still another location which I think is now county land and closed off. That being said the Franciscan Formation chert which yields the poppy jasper occurs in the coast ranges all up the coast from just north of Santa Barbara Ca to Washington state. For example, Big Sandy Creek in Indian Valley, CA has poppy jasper and Stone Canyon like breccia. In addition there are Jurassic chert deposits near Hornitos in the Mt. Williams Range foothills of the Sierra that yield good poppy jasper. Lots of northern CA sites too...Mel

Thanks a bunch! That clears up a lot of my questions. I did hear from sources from around here, that a lot of the MHPJ areas are on private land.

Back when I was in my "ute", I heard one of the Llagas Creek ranchers near where the freeway is now, got so sick of folks trespassing to work the poppy deposit on the creek that he dozered out the deposit exposure and ground it all up to use as road bed material. Think houses got built over a lot of it too...Mel

I remember when the Lions Den poppy first showed up at gem shows. They were selling it by the gram. Supper expensive but probably some of the nicest Morgan Hill I've ever seen and less fractured than a lot of it...Mel

I have randomly ran into some papi Jasper on some Santa Cruz beaches very rare but it was a yellow Jasper with red poppies very pretty.
