A few vials of herkimer diamond, some with fluid inclusions, others with hematite or cavities. These were apparently found by the collector's wife, not the collector himself, as its her name written on the labels.

I'd like to emphasize right now that these things are in no way an effective filtration mechanism for anything, and you should most definitely not pay 50 bones a bottle for any vodka that claims to have been "filtered" with herkimer diamonds.

Cross-section through a piece of dinosaur bone. I'm not a paleontologist, so I don't know, but my friend is and he says that the abundance of red pockets in the marrow there indicates that whatever creature this came from was relatively active. I guess more iron=higher metabolism?

Also, come on, bone sidewalks? That sounds like some kind of Tim Burton-y Halloweentown gimmick. Is this real life or a Warcraft lorebook?

I'll try to keep a steady flow of pictures. Was surprised there isn't some "Rockhound General" or something here.

Finishing for the day with another piece of "Blue Vitriol". Not as pretty as the first, but this time with a locality: Butte Montana. I guess this stuff might have something to do with how toxic the water in that hole is.

>>2151574

how did you acquire this collection?

>>2151574
yeah, it's produced by leaching of copper oxides into sulfuric acid which was known as "oil of vitriol."

presumably dissolving your specimen there in water would likewise produce blue vitriol, sulfuric acid plus copper.

>>2151499
>I guess he managed to get to it before it was declared a national park.
yeah, though collecting fossils in Ntl Parks wasn't always a problem. The fossils belong to the people, back before about 1975 this was interpreted as whatever people happened to find them. Similar situation with cultural artifacts & etc. Used to be you could collect arrowheads and Anasazi pottery and dinosaur bones on public land without a permit.

not so much anymore.

>>2151509
Kinda depends. The large cells are cancellous bone, aka trabecular bone.

this is from the inside of a very large dinosaur bone, likely a sauropod limb bone.

the colors of the minerals filling the pockets are probably not representative of the actual tissues present. The red, e.g., is probably not iron from dinosaur heme. Red cells in dino bone are just common where red inclusions and fossils are found in general. The coloring isn't associated with any particular biology, particularly in agatized bones. It's worth noting that the cell walls fossilize before the interiors do, so whatever is inside the cell has washed out probably millions of years before the interior minerals were deposited. Unfossilized dino bone does show up on occasion, but it's almost always white with black and brown stains. Usually pretty crumbly too.

>>2151617
I don't own it. It was donated to my department by the late collector's daughter in law and I was tasked with cataloging it because I'm the cheapest game in town.

I take my kids up there to hunt pyrite, we find some decent cubes.

It's famous for its gold, here's a piece a guy with a metal detector found a few years back in the road. Currently listed for $2500 on ebay.

I mostly hunt saloon tokens and copper minerals up there. People have dug up tons of gold from the property in the last few years, much to the irritation of the mine owners.

I make more money working for the owners than stealing from them though.

this particular specimen was in the remains of the mine super's cabin. Those Victorian miners loved to collect some rocks.
