These are slag heaps from the many lignite mines in the area.

Connie, I am completely mesmerised by this picture...I did a google maps search of Yunnan, China but could not find this field, could you perhaps give a little more info? are these massive piles of dirt or small hills? Has the photo been photoshopped in any way?
Regards
