Then you say the gorge was cut before any uplift?

No, I am saying the river flowed over the buried formation, and then the region was uplifted. Softer formations eroded away, but the Picture Gorge basalt was more resistant to erosion, so it formed a high aread. The river cut downwards through the formation as it was uplifted, forming the gorge.

Fairy tale nonsense! - What was the rest of the river bed doing while this cut was made through this very selectively uplifted hard material?

As usual we're expected to accept fanciful explanations in place of common sense.

And that would have required water and a active drainage basin over a very long period of time plus a period of time for the present formation to rise above the surrounding area.

Any thoughts on this?
