It may be science, but its pretty soft. Clearly the only things at work here are wind and friction (discounting demons, crop circles etc). What's left could be an exercise left to the reader.

So ok, these guys are 'the reader' and do the legwork. Where can it go? Its not basic or fundamental research; its applicable only to 'rocks on a flat surface'; there aren't a whole lot of places where this will ever be reproduced.

That was what I was asking about: other than the novel circumstance what's to be gained? Got interpreted as anti-science.
