The good ones are in the tumbler. I really just spent 2 hours picking these up in one little hole. gotta do more of these.    This has a pocket that must have had water in it . it blasted away from a 3 pound chunk during heat. dry and wet. Talk about the color 'coral'- sunglasses... dry  wet  |

I gotta get back to this creek. It is a park border. it is kinda park property and public treated domain. It is used as 4 wheel riding area. I think it is 3/4 mile to another great spot i collect oysters at. But it is not seasonally flooded. And it is full of indian pottery and heat treated chips. And apatized ice age mammal bones. And a few unusual corals. And a silicified cast of a sea urchin which are very common but in limestone. Silicified rare. Sea urchins  |

Wow, those oysters are cool. Some of the cuts look a bit like rings in wood. The coral coral with those botryoidal pockets are the bomb. Makes me hungry for fresh trout roe. Those urchins look like decorative dumplings. I bet they would look nifty painted as realistically as possible.

Silicified salmon(salmonid flesh). Warning: Use only diamond dentures to assist consumption.   Salmon Color and the Consumer For the “everyday” color assessment of salmonid flesh, the Roche SalmoFan_ (Figure 2) is the internationally recognized method for color measurement.

The urchins were hung on a tree signifying a 5 star restaurant back in the day.  So. It's a 4 star urchin. |

Nice detail close up on those, is the coral pocket druzzy? (the sparkles)

I think the litter in the river is 1% by weight botyroids and drusifications in a few shoals. Still do not know what the exact process of formation is. |

Next is cabbing them..............sooooooo cooooooool!!!!! I would think the Florida market would be into the local coral. It is the state stone. But it's hard to sell water plants in Florida. Coral may be the same way. Seems the western folks like coral like i like pet wood. But they have coral too. Can't wait to see what you come up with Donnie. |

i really like that orange color! That coral comes up w/some off the wall colors Roy. I just learned that heat treating large chunks takes less heat than slabs. I noticed colors related to higher temps in the center in the larger chunks. Go figure. thanks |

That one with the orange pocket is incredible, I would definately face polish that & display it.

very nice, I have found a few enhydros in the oyster shells before. I polished one too close and it leaked

Your statement about not knowing the process of formation of the corals and oysters is [was] going to be our next question, so much for that. We are thinking rain, normally slightly acidic, and the acids produced by rotting vegetation probably leached the silica out of sand covering everything. Same thing happens here with volcanic ash. Thanks for the additions. Can't speak for anyone else, but the coral we have found here is junk compared to yours, too sandy. Larry

The amount of water in the ground that is flowing is astounding in the area that the coral is found. At my camp at Lake George artesian wells are in every yard down at lake level. At 8 feet above lake level you will have 10 psi of well water pressure. At 16 feet above you will about 5 psi. I am low lander and have about 4 acres(majority) at about 5 feet above lake level. It is high and dry though.
I had 2 wells drilled. They hit rock at the typical 130-150 feet down,drilling through sugar sand the whole way down. Then the action begins and prayers too. They drill into the rock down there hoping to hit a cavern. When they do the well bit free falls and it's time to jump up and down and yell-you will have an artesian then. Then they send 4-5-or 6inch steel pipe down and hammer it into the rock to serve
as a seal and a conduit to send your water up for use. 4 inch pipe at 12 psi = about 100 gallons per minute and 6 inch pipe at 12 psi = about 400 gallons per minute.
The rock they drill down there is all sharks teeth, whale, gulagong and other fossils. and it is colorless chert/limestone colorless due to the colorless sand i presume. One well hit a 20 inch cave/pocket, the other pocket was so big it dropped almost a whole well drill rod of 18 feet!
So, the silica is leached out of this giant 2 mile deep dynamic aquifer called the Ocala Aquifer. It is under all of N. Fl and S. Ga. Wakulla and Silver Springs alone flow almost 2 million gallons of water-per day. And there are thousands of other free flowing springs. I believe it is about all virgin water.Dead clean and sweet to drink. Sulfa in some areas-good for the digester.
That water percolating through limerock carries a lot of crazy minerals and metals and silica. Gobs of silica. That leaching is what causes the cherts and agates and silicifications. Yep. Similar to water percolating through porous volcanic ash. Main difference is colors seem lighter and more monotone than 'ash' agates.
Those springs are often surrounded by desert like conditions for many miles making them ancient sites of occupation for many people.

Look at the 6 inch steel pipe coming out of the canal in the right side of the photo. That is a well. The law came out and made my neighbor(and the rest of us) restrict the flow by reducing down to a 4 inch pipe. So it only spits 100 gallons a minute instead of 400 (with no pump). That well and a bunch of others have not stopped for at least the 15 years i have been going there. So the ground water is very active. Some is hot water. Most is 72F and freeze you.  I poured my own water hole using grain silo for form. 6 panels = 20 foot dia and 7 panels = 23 foot dia. So it has a 1.5 foot thick wall, never to float up. Bottom drain behind chair. 3000 gallons  This pump is real powerful. It is covered and finished. The nozzle in the lower left is massage water. 2 inch to 3/4 inch reduction makes for black and blue bruising if you do not turn it down some. Sit in the bar chair and let it Jacuzzi your lower back. I think it is a 40 GPM at 60 psi pump.  |
