Bob, my mind sees rock or perhaps tree bark but the colors have me guessing. I’m sure this is a multiple exposure but I can’t make out the source images. I like the depth in the image.

Thank you @Alfredo_Mora for your comments. This is a petrified log, so, yes, it is rock and that includes the bark. It is a single image. The colors are natural and made more luminescent by the afternoon sunlight’s intensity and its color. I am attaching an image, full front, when the light was flat. The area of interest, where the posted image was focused on, is the edge of the lower segment of the upper right quarter of the log. The description discuses the origin of the colors.

Oh wow that is interesting Bob. Thanks for providing the context.

Thank you @Alfredo_Mora for your understanding. When I initially encountered this specimen, in the flat light, I was wishing I had an auxiliary light or two. Then, as if on cue, the sun broke through strongly and solved the problem. Divine intervention.
