Michel,
You are very welcome, I had been looking for this shot since i found out about your love of petroglyphs.
I saw probably 50 or so individual sites with 200+ PG's in my area of interest.
Many of the sites had multiple ages, from bronze age - to last week. Once I saw a PG of William Shakespeare, I'm guessing it was recent.
The place name is 5km north of Bayan Ovoo, it is almost due south of Ulaan Batar - very near the chinese border.
The artwork is what suggested the bronze age to the archeo guy. Plus the location is near some copper deposits - this site was within 20-30m away from a small pit (3m X 5m) where people of the bronze age had dug up some copper.
The house is definately a "ger" - the mongol word for yurt - perhaps poorly drawn but up close you could see some details that made me confident.
This type of rock (andesite) was quite resistant to desert varnish - not sure why - but rocks 20m away are black as night on the surface.
Yes definately one guy with a bow.
The guy that came down was a PhD from the institute of antiquities and spoke quite confidently about the petroglyphs - he seemed to know what he was talking about I will try to find some more pics for you.
Hey thanks for the petroglyphs, yeah Mongolia is very rich in petroglyph sites. There seems to be 2 periods on that rock, and strangely it seems to have been made with a blade, which is not very common. The quality of carving is not that good also, which seems to indicate it was made quite hastily. I assume it's on an ancient caravan route. Do you know the name of that place and why they were specifically associated with Bronze Age? I assume it's because of some other figures in the area, as there's nothing on that rock that can be used as a hint for that period, except the fact that the figures were not made with a rock. Does the house represent a buddist temple, as there are 2 floors it seems like, so it couldn't be a traditional yurt? Anyway, the temple or pagoda seems younger than the animals figure. I'm surprised also that they are so light, with no desert varnish (oxydation) recovering those.
EDIT: I enlarge the pic to check more closely, there seems to be 2 horsemen with 4 to 7 goats represented in part or all, probably shepherds, or maybe hunters, as the extreme upper left horseman seems to have a partilly carved bow, but it's too hard to figure out. So this might be the clue to date the art to the Bronze Age at the most.
