Photogrametric scan of drawings on the rocks of a cave in France. I found those drawings fascinating as a kid and as far as I know there has not been much archaeological research done on it.
It is a system of dots and lines, grouped in arrays...
The site was closed for some time and now is open again. So maybe by sharing it, it will trigger some interest and maybe some of you can extract a meaning in these drawings.
The cave is located in France near a town called Culoz.
