I'm sorry I don't have time to give your arguments the consideration they deserve, but I have been spending way too much time on this MB lately. I let my priorities get all screwed up, so let me just make a couple quick responses to all of your posts at once.
Regarding these two pictures I consider nothing unnatural about the formation, so that is why I felt they were of no value. I totally agree with you that they are being caused by a similar process. There are differences between these two and the other picture we were looking at which I don't have time to get into. (They are small and probably insignificant, but it is too early to tell.)
Another note: I don't completely rule out spherical weathering as the cause, I simply have not seen another formation that provides a satisfactory explanation for some of the discrepancies that myself and others have mentioned elsewhere. I will not bother to state these again, but I will say that we must agree to disagree on this point for now.
Other than these points I am withholding judgement on the rest of this formation until I at least know what type of rock we are dealing with and see pictures other than the few that were in the article. We can possibly continue this debate then, but until that time I'm not going to worry about what caused the formation. The important question is whether they are natural or not, and it seems that everyone can agree that they are even if we can't agree on what caused them.
