10 minutes in, newbie here, so dont take this as anything more than me discovering the imagery and how many elements in it demand scrutiny.
To me the layering everywhere there is massive "destruction" appears similar to heavily eroded shotcrete, where layers may be curing before the spray comes back around, leaving layers upon layers.
When concrete is poured it is homogenous throughout typically, but just a short delay on spraying shotcrete can cause layers to form which arent readily visible if the newly cured concrete is cut open.
But add in thousands of years of erosion, and the layers may become very prominent as the cured skin in between them erodes and leaves the layers looking like plies or sheets.
I dont discount these features also may be petrified wood.
I just randomly picked an image or two and did quick PS on them, and am seeing these features to be pretty suspicious on their face without heavy processing.
Forgive me if these are already known, this was just my first delve into this whole thing to appease my own eyes and brain..lol.
This first one shows a 3 dimensional corner with what appears to be a reveal or raised kerf profile on the top of the corner. Also lots of layering, as if sprayed(built up) in different layers over time.
The second one shows very detailed obvious layers, with the fast cured "skin" between layers eroded away leaving the slower curing layers which are the primary part of the sprayed or built up structure.
The possibility also exists that this is fossilized or petrified woodgrain.
The third, well it reminds me of the base of the Great Pyramid, where the casing stones are missing and there are blocks built on top of an angled base, here the two are slid apart, and the mortar or adhesive layer can be seen as a separate skin on the left inside of the angled right block. Bottom left there are several marks like a large flat pick or router type tool was used to router out or scrape out the groovelike notches that go in a shallow cut into the face of the block and down into the ground/surface.
The deep horizontal groove on the right angled block speaks for itself.
It took me longer to assemble this post, than it did to find and lightly process these features.
I see where your passion ( or some naysayers may say "obsession") comes from Jimmy!
