Nice! I lie small spheres. I ran into a guy on a rockhound trip one time that kept his rock collection in a pouch in his pocket. He had him one of those marble machines I guess, and would make a marble from the best example of a particular material he could find. Basically a small sphere collection. I thought that was pretty cool.

We're having a mild summer heat wise this year in the Texas Hill Country but the humidity is bad enough I have to change clothes several times a day. Wet and sticky seem to be the current state of affairs this year.

There is a somewhat similar dendritic agate from several locations in Wyoming and another from near Valley Springs, CA but the pictured type is definitely Parral.

Yep, Parral Dendritic Agate. No doubt about it.

Wow great plume cabs! Really like the one with the red/white color blend.
Those mudflat sculptures are very cool too. Both the wife and I were East Bay kids and I remember that being quite the thing when I worked for the Cal State Hayward research foundation on a bird project that had me visiting all the bay shore areas.

Leopardskin is a favorite material of mine too but man the stuff varies in silica content. Some takes a very high polish and other pieces are so porous they just suck up water and it's impossible to achieve better than a satin finish. I bought some of the most beautiful red and black stuff only to find it's in the latter category. I've found the best bet when choosing rough or slabs is to put a bead of water on the surface and see if it is absorbed or not or just to dip it and see how quick it dries.

Specular hematite bands in some kind of matrix. Found in igneous, metamorphic and sedimentary deposits.

That green moss is Indian Green Moss from the Deccan Plateau region. That last brecciated piece is pet wood that's been fractured and rehealed. #1 does look like pet wood #3 also dunno but has a stromatolitic look to it.

Yep, Willow Creek for A. The two mosses could be from so many places. The rhyolite looking material sure reminds me of bullseye jasper from Goldfield, Nevada but Nevada has a lot of good rhyolite locations.

Wow! I've never found a cache in many yeas of hunting but I was in a cafe in Eastern Oregon one time when a guy came in with a rawhide bag full of atlatl dart tips on their little hardwood shafts abut ten inches long, plainly to be used as replacements for lost points in a repeating lance or dart main shaft. He found them in a little cliff shelter in a woodrat nest. Very old stuff . Looked like Paleo points to me and beautifully made of obsidian, jasper and what looked like pet wood. I have a single similar jasper point I found in that same region on the California side while deer hunting but finding about a dozen in their original bag wow, what a find!

Yeah, it's almost like finding a little treasures. This area was treaty ground where many tribes over many centuries gathered to mine chert and knap, primarily trade blanks, for easy transport but there are also many campsites here. Most the artifact hunting was done in the 1970's when the place was first developed and the first residents amassed huge collections but erosion and animal activity always exposes a few new finds every year. The Most common material dates back about 4-5000 years as most campsites here were the Pedernales culture, a pre bow and arrow culture.....Mel

If you want something pretty close to home, a nice day trip is to be had in Mariposa County. Take White rock Road about two to three miles NE of Westfall RD junction. The site is near where there will be two small ponds about a mile apart on the left side going up the road. The good dirt road cuts through a huge bed of Chiastolite crystals. White crystal sections with black crosses are all over the road bed. Just keep checking the road as you go up. Easy to find as the deposit is about 1/4 mile long. Whole crystals are sometimes found up to 2-3 inches long, 3/4 inch in diameter. Most are just crystal sections. Exteriors with sparkly pyrite. Motels in Mariposa, which also has the State Mineral museum which is well worth a visit too.

Very nice but it has me stumped. Never seen that except in Ocos. However, Ocos do come from Rio Grande do Sol where Brazilians come from and form the same way as gas pocket nodules. Best guess would be a large Oco solid or an off type Brazilian.
PS: Went into my Johann Zenz Agate Book Volune #1 He calls those "Cloud Agates" and they are in his Brazilian Agate section. Has a nice pic of a solid example. Not fortified like yours but also that caramel color.
