This is such a cool rock formation and you have captured it beautifully. The combination of the lovely blue sky and the wonderfully warm colours of the rocks and grass is just perfect. Great work.
Reminds me of Silbury Hill in Britain (in minature), which is a man-made rock mound (which may have interior chambers) that was covered with earth. This definitely looks man-made to me, but either not covered by earth or the earth has washed off it. I wonder if anyone has applied to excavate it.
