It didn’t get a 5 darn… it will.
There are the ones that have no light in their eyes at all too.
Lets see if I can give you a synopsis.
That creek in the park has always been where it is; it hasn’t meandered back and forth since the sand was deposited. Or else it would look like where I’m going to mine.
The layer that is under the sand has to some extent and was moved and polished, since 99% of the rocks in those two layers are round and smoother after the ice age, or during the ice age, under that layer is some rougher stuff that the glacier was in process of moving and hasn’t moved far, below that is bedrock.
The other spot where I am going to mine the creek is a lot bigger and it has meandered back and forth some.
Everything it has piled up, is mixed up and laid down fast, faster than a glacier and then it jams up and changes course. This is from flooding that is normal, it also took out a section of the older giant sand wave and so it gives us a cross section now that’s fairly clean.
But it will never make a deposit of sand as big as the sand wave.
So the sand that is on the top layer can be about 12,000 years old give or take a few years.
It’s on top in the park and it’s totally different than what the river courses deposit, it is loose too. Like the dunes in Indiana.
There are only Maybe six till you hit bedrock in the park the heart of the valley, the central low spot.
To deposit this amount of sand would take an ocean to make those layers and it happened, after the glaciers receded.
There are some clays in there and that’s what makes it semi sticky or hardened
Two things had to be mixed together.
So this valley is east of the pacific and if water was deep enough past the tops of the mountains here, it would have to breach 3500 foot elevation the currents would be west to east that would explain why the big sand wave is on the eastern slops of the valley and why the sand is level in the central part of the valley.
The next valley over which is 25 miles from here is the same and when I go there I will film those sand deposits. I will show you the clays that the glacier made and what it’s consistency is like. Same there about 6 layers on top of that the last layer is about 4 to 6 feet of sand.
Joobz you must of lived in Michigan City or thereabouts and you have stood on the lakeshore so don’t you think there should be more sand there?
Where did it go?
I think the dunes that where there, were much bigger at one time and they got flattened and mixed with clay and pushed down into Indiana and quickly with a great wall of water.
What are left are the parks and dunes we have now.
They are awesome.
But there should be more and rows of them, halfway down the state.
There probably was since the lake and the glacier extended down into Indiana almost to the Ohio River.
We know the this event had to most dramatic effect in the Sahara and the sand on top covers a forest that was there about 12,000 years ago.
The gold that’s here is on the bottom; because the glaciers were scouring the bedrock and tearing chunks out of the veins near the surface that were protruding in all ways and directions/angles…and making them smooth too.
Some ruff gold is found and always near the source and weathering and gravity pulls these pieces and moves them with the newer forces but the smooth gold moved with the same forces that polished the other rocks, This is why the tiniest pieces of gold are usually smooth too, but they started out as bigger pieces.
Where do you think all this sand came from?
Remember in geological terms it was one of the last layers put down on top; the last two are humus, and mulch.
Unless a giant flood in the last 3000 to 12,000 years didn’t do it, normal erosion and flooding wouldn’t make those amounts of sand, let alone settle it in the huge areas that I have been to and recorded. That amount of sand being made in six or 12,000 years won’t happen by erosion only.
Hardened blue and brown clays are the finer deposits of clay that the glaciers set down on the bedrock or real bottom then there are only 6 or 7 layers on top of those and the last layer of light material on them is sand 2 to 6 feet or so deep top layers that haven’t been cut through by water pressure from rivers or creeks.
To the left of the dredge is brown stained clay but inside it's blue.
That's known as a false bottom but it collects from further uo stream what's moving with todays currents and traps the gold.
If you could go between that layer and true bottom we would find more and bigger gold.
