15 MORE UNDERGROUND STRUCTURES AT STONEHENGE. This month’s Smithsonian magazine has an article by Ed Caesar about the discovery of 15 more underground structures at Stonehenge—henges, barrows, segmented ditches and pits. The results came from an underground survey over more than four square miles. The survey used ground-pennetrating radar and magnetometers. The magnetometers map variations in the earth’s magnetic field. The new evidence suggests “a scale of activity around Stonehenge far beyond what was previously suspected.”
This survey is the first attempt to find out what lies below the area near Stonehenge. Only digging would reveal more. However, it is remarkable how much has been discovered in the few years since we visited Stonehenge and Annalisa pointed out that it looked like there was a lot more that could be found out.
