Here is a full resolution crop of the right side of the image I posted above, in the area of the rectangular cutout in the figure:
You'll notice upon close inspection, there isn't any noticeable difference in the the surface patination between the surfaces inside the carved
areas, and the surfaces of the uncarved rock.
What is perceived as a 'lighter' color, on close inspection, is actually a thin deposit of mud or silt, combined with the glare from the water,
which was due to the rainfall at the time, not from the stream. The surface of the rock is far enough above the stream to be dry at the current water
level, if it weren't for the rain.
The actual color and shade of the carved rock, where it projects through the silt, is the same as the surrounding uncarved rock.
It's supposed to be dryer tomorrow, so I'll try to get up there and take better pictures, maybe some macros as well to get a better view of the
surfaces, and include the requested measuring devices for scale.
With that, I'm off to bed, and will check in again tomorrow.
