on the sunny side of my rock image, there are long chains of a material, not part of the rock. In the shadows, with arrow, encrustations, with one having a, er, ah, ependage, the other?. in the soil, ground bloom, with one coming out of ahole, the other on of the odd globular clumps, right next to the rock.
The phoenix images have many more features that show the dynamic conditions prevalent in this environment.
