Something I’m working on at the moment is to try georeferencing every mention of a rock art site in Southeast Asia on a Google Earth map. Here’s the current work in progres:
Reds are painted and drawn sites, Blues are petroglyphs, and Greens are megaliths. I have been on record before saying there are at least 400-600 known sites in the region. My current count is somewhere close to 1,400.
Now that’s a lot of rock art.
