Reading Tracey's piece, this isn't simply a Black Range issue. While that's the primary focus here, this discussion will include The Grampians. There are important crags here that have bolts next to art sites and bouldering sites close to, if not actually in, cultural sites.
A good starting point is to understand that the local indigenous people are at least as passionate about their cultural sites as we are about our climbing and bouldering sites. A few years ago I had the great priviledge to accompany an indigenous ranger into an obscure art site that I had stumbled across. His absolute delight as he photographed and catalogued it was amazing.
Please engage with this process as it rolls along. Remember that we're engaged in a first-world sport that's coming into contact with a very old culture.
