In Canada, there are rock art sites from coast to coast. The exact number of sites has yet to be determined, but some 3000 sites are believed to exist. As elsewhere in the world, the assessed number of sites remains approximate due to natural (erosion) and anthropic (vandalism) destructions.","thumbnail_url":"https:\/\/imagesdanslapierre.mcq.org\/wp-content\/uploads\/2019\/01\/ou.jpg"}
