We Never Know

I don't know why he brings up these red herrings. At any rate the limestone that was eroded was not what one would call pristine. It appears that there was significant weakening of the area ahead of time. The gorge follows a fault trace as shown here:

Perhaps if he could make a clear point as to why he even brought this up in the first place.
Really!
Look at post 102.
Look at the post I replied to claiming the grand canyon was carved by the great flood.
Instead of just saying you're wrong with a hand waving him off, I thought I would show him that yes sometimes a smaller canyon can be cut in short time.
Then went on the explain it isn't evidence of the flood or the flood cutting the grand canyon. And how with his biblical flood, the whole earth being covered in water, with the sea level only dropping 79 feet per day, that the water wasn't receding fast enough to cut a canyon.
If that isn't clear for you, I can't help you.
Your mistake was jumping in without reading all the posts and thinking I was trying to somehow support a great flood. Your error, not mine.
