wow, CTD, you've outdone yourself this time!
The insightful and thoughtful already know how your boomerang has whomped you up 'side the skull. I'm just providing the equivalent of a slow-mo replay for those who haven't focused their attention sufficiently, or are having trouble seeing through the smokescreen.
Using the existing canyon to say that it cause the canyon to form that way is a circular argument and a post hoc ergo propter hoc fallacy.
If that's how you feel, I hope we'll see no more of it from you.
Fill that canyon to just barely over the brim, to envisage how it would look before any canyon was carved, and then show me where there is an obstruction.

PLEASE DO THIS, people, if you haven't already done so. Please envision the river flowing on flat ground at the level of the top of the canyon.
Got it? Now apply the meander-cutting abilities of even a small, small flood to this river. Wouldn't take much, would it? All that evotime, all 700,000 years, or 3 million, or 10 million, or whatever... To be sure,
all that imagined time is not involved - only a percentage. I want to be clear about that. But we're still talking several tenthousands of years with the meanders failing to be cut by any floods.
Does that qualify as special pleading? Well you ain't seen nothin' yet. Actually, if you read RAZD's source, or even the bit he snipped, you've seen this, but it'd be easy to overlook. This is extra-special pleading because
The narrow neck of land between the two neighbouring concave banks is finally cut through, either by lateral erosion of the two concave banks or by the strong currents of a flood.
Even without a single flood in all those tenthousands of years, the river would still be able to cut through the narrow neck of land and straighten this meander, possibly leaving an "oxbow lake" or fossil "oxbow lake".
Catch that Linear? That's twice RAZD's story differs from his own source.
So what's next from our evocrew? More closed eyes? More pretending to be too stupid to understand? More pretending I haven't posted anything? Perhaps some ad homs against the wiki author? If you guys're so intent on repeating history, why not dig back into the past & try something that hasn't been done
recently? You know, just to keep it interesting...
