THE NEW CIRCLE

In 2001, a National Park Service team was using their new remote-sensing equipment out here, near the center of the Hopewell enclosure. One afternoon, this startling image appeared: it was a long-lost earthen ring and ditch, completely invisible to the naked eye. It was 100 feet across, and perfectly circular, with a gateway pointing east. It is typical of earlier, Adena-era earthen rings, so may have already been here before the larger, enclosing earthwork was built.

This magnetometry image is typical of how remote sensing instruments can detect ancient earthworks now invisible on the surface.
