I'm confused: Your post on the canyon erosion (re: amphibolite erosion thesis) was in response to my original post (2,632) from myself to abb discussing a "flip" dispersal system at the plunge pool ("The end of the broken spillway.."). This discussion was specific to the article abb posted to me. btw- I clearly understood the "flip" design proposal. The article clearly states that the proposal is to make "water jump the gap" i.e. Jump over what is called the plunge pool.

Then I responded to your amphibolite post & pic to me with post 2,636 demonstrating a simple proof of structural & functional soundness when concrete, properly emplaced in amphibolite with a "flip" dispersal system at the end of the original spillway.

Was there a misread of my original post (2,362) in discussing the challenges of anchoring a "flip" design at the end of the damaged spillway?

I didn’t comment on a flip or plunge pool, only on the hardness of the rock. Your reply discussed a flip at the end of the spillway. This was puzzling since I hadn’t commented on that. So I scrolled back to see where the flip pool was discussed and found the article which proposed trying to jump over the crater in the spillway. This differed from a flip at the end of the spillway, hence my comment.

We were talking about two different things and talked right past each other.
