Prosecutors say 58-year-old Christopher Harp sprayed a black substance on several large rocks, including one depicting a bighorn sheep. Special Agent Brian Adams with the US Forest Service says Harp admitted to the graffiti. He says Harp claimed he was getting revenge on his boss for talking down to him. Harp told the agent he was drunk and didn't know the rocks had historical value. He has pleaded not guilty to charges he damaged the rock. Court records show Harp has been placed in treatment.
