ADAMS COUNTY, OHIO—A 19-year-old man who has confessed to taking a joy ride over an ancient earthwork near Serpent Mound could face prison time, more than $3,000 in damages, community service, and a research paper. “He has been cooperative, so we’re working with him. But I don’t think he appreciates the significance of the site, the gravity of what he’s done,” Adams County Assistant Prosecutor Ken Armstrong told Cincinnati.com. The young man allegedly jumped the curb of the parking lot at the monument and drove his pick-up truck over a 2,000-year-old Adena mound. Park Manager Tim Goodwin says the tire marks will be repaired by replacing the sod. Acts of vandalism at the site are rare, but Goodwin explained that additional security cameras will be installed. Serpent Mound has been nominated for UNESCO World Heritage status. “It deserves the respect of the world,” said archaeologist Brad Lepper.
