Officials with the Elbert County Road Department brought in an excavator to dig down the required six feet. Using a tape measure to ensure accuracy, the only thing officials said they found when workers hit the six-foot mark was more dirt.

This, of course, is in sharp contrast to a meme going around on various social media sites, which claim a signed issue of Playboy magazine featuring Burt Reynolds, a Peterbilt emblem, an 8-track of the "Saturday Night Fever" soundtrack, and several dozen Quaaludes were found in a box. All clever throwbacks to the era the stones were erected, but not anything that was actually found beneath the wreckage.
