No legitimate geologist considers them to be water deposited. It must be a conspiracy.<quoted text>
I have seen Coconino-image depositions within the Tapeats, angled patterns and all, very conform and very much water deposited. Its still a sandstone - sand dunes don't homaginize well, no more than lithify into concrete hard structures without water and 'lime'.
Take the Cottonwood trail down to the creek and follow it down, you will see both. I am a novice to the canyon, but had guides that have over 25 years working there. Don't know about tunnels, sorry.
The tunneling is fossilized evidence of marine animals. According to your belief, they had time to work around in the sediment and apparently thrive while under the pressure of a tremendous water column. This evidence doesn't fit your belief-based version, but fits the accepted geological model.
