A Georgia man discovered that the federal shutdown of the national parks didn’t mean he was free to illegally dig for artifacts at the Kennesaw Mountain National Military Park.

If he thought no one was watching, he was wrong. Two National Park Service rangers as well as a Cobb County police officer saw him walk onto the battlefield carrying a metal detector and a shovel.

When the unidentified man returned to his car, law enforcement swooped in to arrest him. They found that he was “carrying several objects that were from the Civil War period,” as a ranger described the situation to a TV reporter.

The artifacts were seized and the man faces several federal charges.

A Park Service archaeologist is usually called to the scene of an illegal dig to check out the area, but according to a newspaper account, the one for that area had been furloughed.
