Barrier Canyon Style Fremont "ghost" panel. These nearly human sized pictographs are between 1500-4000 years old.
Of course, I'm not of the culture that produced this imagery, but I do wonder why they chose such an irregular surface for the images when nearby there were perfectly good flat surfaces?
(Note: I isolated the images using a parametric mask in the rgb primaries module in Darktable & upped the saturation of the red ochre pigment used.)
