When you know your postion is right and not subject to being changed based on the evidence it IS a religious position.

compound/complex forces
If you have access to that set up would it be possible to get some images of compound forces; for example if the stress point was slanted vertically (both slopes) or squeezed at an angle (stress to front/stress to rear)?

Edited by jar, : fix sub-title

Re: compound/complex forces
I agree but just hoped we could duplicate Faiths objections to satisfy her.

Long long ago and in a land far far away, when I was in what today would be middle school, the teacher (in a Christian school by the way) let us do similar experiments but we used sand and gravel and clay and got similar results with the added benefit of seeing the clay deformation both initially and over time. The clay showed some plasticity and continued deformation as it dried with cracks forming and the sand layer intruding into the cracks in the clay layer. The gravel also tended to work down into the sand layer where those two surfaces met.

But that was long ago and of course may not behave that way since the Fall.

telling the tale
Can you tell us a little more about those beds. It certainly looks quite different than the Hawaii lava beds and what would that tell us about the origin, age, environment at the time they were laid down and environment since they were laid down?

Besides, the ashfall deposits may not have been a single continuous event. There is layering within the deposits.

How can you know that is the case?

In the bottom picture above is the ash the white slab like pieces at the bottom of the picture?

So are you saying that in the pinnacle the topmost tan material is sandstone?

Is the greenish part below that volcanic ash?

What is the tan material at the bottom?

Yes, and there are several layers of it.

How do you know there are several layers of it?

You've mentioned coal seams several times. How would a coal seam get formed?

Swamps and bogs are one thing, mud stone and shale another, but how can actual coal be explained?

So you are saying that there are actual layers of coal between layers of volcanic ash, correct?

Edited by jar, : No reason given.

I'm simply looking for information.

You have said that there are layers of coal found between layers of volcanic ash and also layers of sandstone.

We saw pictures that show a layer of ash with sandstone above and below.

The topic is the story in the rock. Tell us the story (hopefully with actual pictures not drawings) that those rocks tell you?

You mention a coal seam burned. Is there evidence to show that the coal seam was buried when burned and not simply a wild fire?

So just to check.

There is a layer of sandstone.

Then there a layer of volcanic ash that is many meters deep.

Then a layer of clay or mudstone.

Then a layer that was once a marsh or bog over the volcanic ask that was later covered by another volcanic ash flow and the bog or marsh material compressed and turned into coal.

Clay that was above and below the coal layer was later baked by a coal seam fire.

There are additional layers of Sandstone, volcanic ash, shale or mudstone above the coal seams and in repeated iterations.

And finally there is sandstone at the current surface.

If that is correct, how did the sandstone instead of soil or marsh or bog or woodland like we see when we walk around today get to be the current surface?
