^ You obviously expect us to believe your hearsay on a critical point.
I have read and skipped through dozens of stratigraphy books. I would simply not be able to make the statements you are making from them. Unless I am mistaken, you have simply gained an impression about the 'canyon strata and are expounding gross simplifications.
I often do that too - but at least I'm arguing feasability there not outright ruling out a model like you are.
