Lincoln Mysteries

The patterns embedded in the ancient surfaces of Lincoln Rock (sometimes known as "Flat Rock" - near Wentworth Falls, Blue Mountains) are a wonder to behold. You need to be a little brave to approach the edge (and its breathtaking drop) but the surface markings are magic. Some form of solidified lava perhaps or long term water erosion at the edge of a primordial sea, possibly. Anyway, I thought it made a nice image.
