Eileen Townsend at The Paris Review:
If you’ve ever taken I-81 north through Virginia, you’ve passed the town of Natural Bridge, in Rockbridge County—home to a ninety-foot limestone arch that extends over a gorge, a geological anomaly probably formed by an ancient underground river. Natural Bridge is an anachronism from the Route 66 era of highway travel, a place where you can pay twenty dollars to look at a rock, eat a rock-themed lunch, and then buy a shot glass illustrated with a picture of that same rock. As any respectable tourist trap must, the town hosts a constellation of other attractions: a petting zoo, a dinosaur/Civil War theme park, and the Natural Bridge Wax Museum (now closed, and former home to a ghoulish Obama tribute). Best of all is the featherlight, faux prehistoric monument known as Foamhenge.
As its name suggests, Foamhenge is a one-to-one scale replica of Stonehenge, made of foam. It is identical to the original, save the flecked gray paint, the accompanying statue of a deadhead-ish Merlin, and the fact that it was erected several millennia later. For the past twelve years, the henge has been the most public of Natural Bridge’s draws, garnering a steady stream of visitors and enough press to be mentioned in the same breath as the area’s actual ancient rocks. Its creator, an artist named Mark Cline, calls it his “foam-nomenon”: the unlikely culmination of his career as a sculptor of roadside attractions.
