As the legend goes, a foghorn could be going off in the center of the circle and those on the outside wouldn’t hear it. This may be an exaggeration, but your voice does sound extremely distorted when heard from outside the circle. It’s an incredible effect.

Like the Lake George Mystery Spot—another acoustical vortex that seems to defy the laws of physics—the effect is thought to be caused by the sound reflecting off a circular wall, in this case a nearby planter. Still, though many people have studied the cause of the odd anomaly there’s no clear consensus. Whatever the causes of this natural sonic distortion may be, it is truly an amazing place.
