I think this has some possibilities however, it needs some work.
I used Strata and Outcrops, Twist and Shear and Heightfield Erod. Also, Fractal Shaders.
I welcome any suggestions to increase the realism.
I am flying solo on this, not using tutorials or other created terrain files, to see what I can come up with.
I included the file which you will find very elementary.
Thanks.
