So sandstone is hard? Who know?

[gnarledmaw]

I would imagine that nearly everyone knows that sandstone limestone is very hard by comparison to silt which is what we are discussing.

And the issue isnt just that of relative hardness but the idea of being able to create those formations from the slow removal of nearby material. I believe that this kind of depth to width suggests a large amount of the surface exposed and the water has some degree of force behind it. It doesnt require a geologist to point out the difference. Just about anyone living in an area with limestone outcroppings/caves should be able to show someone the difference in damage to the rock between dripping/draining and a flow with even minimal force behind it.

Its not just my theory. Its not just a theory of Schochs. Christianson believes these were created by rapid water movement and in the ancient past but he believes it happened in faults before the Sphinx was even quarried. Lehner claims there was a period of climate change. Climatologists Rudolph Kuper and Stefan Kröpelin, feel that it was just wetter there longer than the dates presently accepted by most. They all believe the answer involves more water, none of them can agree on when it was.

Its true, there are those that believe very small amounts of water were involved. Some believe small amounts of water drove the process of haloclasty, they just dont exactly agree on how it got there. I would have to see evidence of some type of fault that would allow some areas to deteriorate to such depths compared to the entire surface before I were willing to consider this as the sole answer.

The point being when it occurred and exactly how it occurred certainly isnt settled science. Maybe there was more than one factor involved. The one theory that cant explain it is gradual pond dredging and certainly cant explain it on its own.

None of that gets into any of the other problems with that theory. The fact is that none of these theories are hills I plan to die on, youre going to have to write to them. I just know that my tombstone wont be on the pile of dredgings.

I’m not going to argue with you because you must know more than the guy who actually went there photographed it, founding evidence it was the result of vertical dredging and explored the areas that are closed to tourists and not visited by anyone in over a century.
