Beneath the Rocky Mountains in Colorado, scientists have detected a massive, mysterious anomaly buried deep underground, and their own findings have unsettled them. The discovery emerged during geological mapping, revealing a gravity anomaly that defies standard explanations for the region’s structure.
Colorado sits above a geologically active foundation that continues to shape its surface. 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…
