Actually, this one is less insightful than many of his other ones. Found it unfulfilling.
I don’t find him to be insightful at all, it’s always “this could be from 1000 years ago”. He hikes out, and after a lot of rigamarole and narration he finally shows fleeting images which are an awful lot alike in every one of his videos — remains of a wall in a crack in a cliff face, petroglyphs, then panoramas of the surroundings.
This one was loaded up with a lot of different stuff, and I didn’t use the Roku this time, so skipping ahead was simpler. He spends a couple of minutes near the beginning doing an ad for Opera.
