A massive, hidden void has just been detected beneath Stonehenge, and experts are calling the discovery deeply unsettling. Ground-penetrating scans of the prehistoric monument’s interior revealed a huge underground cavity that no one knew existed.

Geophysical surveys around Stonehenge have identified a substantial underground complex of pits, ritual structures, and buried monuments surrounding the famous stone circle on Salisbury Plain. The scans, conducted as part of the Stonehenge Hidden Landscapes Project, have revealed a far larger ceremonial landscape than previously known, much of which remains unexcavated.The project began in 2010 as…

Deep beneath the state, the lithosphere was weakened by ancient subduction, and the ground is still rising and shifting today. A supervolcano in the San Juans erupted millions of years ago with far greater force than recent Cascade eruptions, a mountainside near Lake City creeps steadily downhill, and in the…
