No, what Faith says is that there is no" erosion" within the geologic column that deserves to be compared with the massive erosion of the surface we now live on, ...
Faith, what evidence do you have for this? How would you know, by looking only at the surface, whether or not there is similar erosion in earlier strata which have been covered up? We can look at the earlier strata through 3-D seismic imaging. If we do this, we find similar evidence of erosion to what we see at the surface. For example, we can see buried river channels which were cut into these layers when they were exposed. How do you explain such buried river channels from a YEC perspective?"Science without religion is lame, religion without science is blind." — Albert Einstein I am very astonished that the scientific picture of the real world around me is very deficient. It gives us a lot of factual information, puts all of our experience in a magnificently consistent order, but it is ghastly silent about all and sundry that is really near to our heart, that really matters to us. It cannot tell us a word about red and blue, bitter and sweet, physical pain and physical delight; it knows nothing of beautiful and ugly, good or bad, God and eternity. Science sometimes pretends to answer questions in these domains, but the answers are very often so silly that we are not inclined to take them seriously. — Erwin Schroedinger

I don't know it from looking at the surface, I know it from all the cross sections that have been discussed here.
I don't accept that the seismic images show formerly surface features, but rather features that developed underground. There is so much evidence that the strata deposited continuously over a short period of time such very occasional internal features could not have been on the surface long enough to explain their dimensions.

Certainly could. They are different ages, of course. I'm not sure about how large or thick the sand hills are, but if they don't erode away, they will form a desert sand deposit in the current geological record. Or if Faith is correct, the geological record is dead and nothing will change, ever...

Is there an answer to my question about how thick shale layers great in extent form?
They typically form in basins or on wide continental platforms that are inundated for extended periods. The Manco Shale is one of the large ones that I am familiar with and it formed on the bottom of the Cretaceous seaway in central North America over a period of about 15 million years. Here is a stratigraphic correlation chart for the Mancos.
What it shows is the Mancos Shale, and its equivalent, the Pierre Shale, in gray, do not extend to the west where the Laramide mountain building event was occurring. In yellow, 'tongues' of sand stone such as the Dakota up to the Fox Hills extend from source areas in the highlands to the west, eastward into the Mancos basin. These represent times of marine regression as sea levels fluctuated during the time of the seaway. Just for fun, here is a cross section of the Denver Basin sequence which is underlain by the Pierre Shale.
AFAIK, the Pierre is eroded away east of the Dakotas. Not sure if this answers you question, but these are truly important geological features of the planet. Edited by edge, : No reason given.

Of course. True things can't be true if they contradict your beliefs. If only geologists knew that, then they too would attribute the geological record to the magical activities of a malevolent invisible loony who lives in the sky, like sensible people do.

Christian geologists, who specifically set out to find evidence of the flood, realized this hundreds of years ago. Edited by 46&2, : No reason given. Edited by 46&2, : No reason given.

A total draft first attempt at a video put together for a family member who is trying to understand dating methods. It's not public on YouTube nor will this one ever be.
I'm putting together three of these for her -- meant to be in the order of how the age of the earth was figured out. First through relative dating (this video) then later through the observation of geologic processes such as deposition and erosion (next video) and then finally through RM dating (final video). Just posting it up to show what I've been up to (and to say thanks to the many who have been helping educate me). I truly don't expect folk to sit through a 30 minute vid of such basics. Here is what I emailed her with the video:

They were looking in the wrong place. How could they look in the wrong place? The flood was GLOBAL.

They were looking in the wrong place. They looked in the geological record instead of in Faith's imagination.

Yeah, they looked at reality instead of their own fantasy worlds.

They were looking for the evidence in particular layers, not in the entire geological column. Some people still have that wrong idea.

While SO may people contributed and continue to contribute to my knowledge regarding the basics of geology, I want to especially thank Dr. Adequate and Edge for their patience and sharing. The online ebook from Dr. Adequate was a particularly valuable resource.
Thanks to all. JB
