Mesa Verde National Park is asking for help combating graffiti, vandalism, and littering. In a recent Facebook posting, park officials say over the summer they have seen more and more evidence of such behavior. Spokesperson Christy Brown tells KSJD in a recent incident, a vandal dug up prehistoric charcoal from an archaeological site and used it to rub names onto sandstone. The charcoal was completely used up. In the Facebook post, park officials urge visitors to contact staff if they see anyone engaging in such activities. The post has been shared more than 1300 times, and Brown says it’s even made it “across the pond” to the Daily-Mail news outlet in Great Britain.
