The textures on the far left side are particularly interesting. Love those lichens on the middle-right side.

The closer I got to these rocks, the more intriguing were some of the erosion patterns. I only wish I was able to understand exactly the ancient and recent processes of their formation. Enough for the moment that I find the resultant textures and patterns a marvel of nature.
