Petroglyphs are new to me. Exploring this boulder field near Lake Issyk-Kul near Cholpon Ata in Kyrgyzstan is a highlight experience in my museum career. Mining history circa 1870 is about as old and rocky as I get, but these from 500 BC opened new doors to history.
The question was, How/If to make them accessible to the larger public? This site is a newly-discovered source - at least for non-herders. There's a well-known, well-mapped site not far up the road.
In this case, the more sustainable museum is the one not built.
