If television presenters can get to it, where are the archaeologists?

Tantalizing. I keep seeing news about the discovery of a massive cliff face in a remote part of central Colombia that is covered with ancient rock art. This would be really cool, except that I’m feeling suspicious and skeptical. But look at this image! I want it to be true.

There are a few reasons I’m dubious right now. I don’t doubt that the rock art is there, but I’m seeing claims that it’s between 20,000 (as reported in 2015) and 12,500 years old. What I’m not seeing is citations to the scientific literature. The recent surge in interest seems to be fueled by the upcoming release of a television program on UK Channel 4. For all I know, that could be equivalent to an announcement that it’s going to be on the History channel, which would tell me it’s garbage and hype. Does anyone know if there is a paper in an archaeology journal about it?

I just like the idea of seeing more art by witnesses to Giant Ground Sloths.
