Beneath nearly a mile of Antarctica's ice lies a landscape frozen in time for 34 million years.In the remote Wilkes Land region of East Antarctica, scientists have mapped an immense, pristine prehistoric world completely preserved under more than 5,500 feet (1.7 km) of ice. Covering roughly 12,000 square miles—an area comparable to the state of Maryland—this buried terrain includes towering highland plateaus and dramatic river-carved valleys plunging up to 4,000 feet deep.Using advanced satellite data combined with airborne ice-penetrating radar, researchers revealed a network of ancient river channels and rugged topography that dates back to a time when Antarctica was far warmer and greener—likely blanketed in lush forests and teeming with life—before the continent became locked in permanent ice around 34 million years ago during the Eocene-Oligocene transition.What sets this discovery apart is the extraordinary preservation: unlike most glacial regions where moving ice grinds and reshapes the bedrock, the ice sheet here has stayed remarkably cold, thick, and nearly stationary for tens of millions of years. This has turned the landscape into a near-perfect geological time capsule, shielding it from erosion and environmental change.The find opens exciting possibilities for future research. Scientists are now developing plans to drill through the overlying ice to extract samples of the ancient soil, sediments, and potential organic remnants trapped below. These materials could provide unprecedented insights into Earth's ancient climate, the processes that triggered the formation of the Antarctic ice sheet, and how the planet transitioned into its current icy state—offering vital clues about past—and potentially future—climate dynamics.[Jamieson, S.
