Lost cities / archaeology / ancient history

Oh, excellent. That looks utterly fantastic. It also does one of my favourite things, which is that it seemingly confirms that humans got there earlier than previously suspected. As I've said many times, I think we'll continue to have to push back the chronology much further than where it stands at present. In Australia, we're up to about 60,000 years ago by some estimates, and I expect that people have been in the Americas for much longer than we have so far assumed.

This is a nice little gallery of prehistoric rock art, some about as big as this latest discovery:

As you imply with your '' around 'discovered', the site will have been very well known to local people.
