[meteorite-list] Northern Central Asian Impact petroglyphs?

[E.P. Grondine]

Hi all - 

Thanks for tracking down those images and reports.

Since I lack intimate familiarity with the culures in the area, my comments will be limited.

The comments about the re-use of petroglph sites and the difficulties in dating petroglyphs are valid in my own experience. The only thing that can clear those problems up are excavation and geological field work.

As I have work to do on 3 North American petroglyphs, I hope you will forgive me for not pursung this, except to read the reports, and thanks for your help on that. 

Of course, one big question is always asteroid versus comet impact.
In the first case, meteorites may be found, in the second, finding impactites is tough.

good hunting, 
Ed
