Pink granite boulders high in the Hudson Mountains point to a massive buried granite body beneath Pine Island Glacier. Airborne gravity data map a ~100 km by 7 km subglacial mass dating to ~175 million years ago, offering new insight into past ice flow and helping refine models of Antarctic ice dynamics and sea-level rise.
Scientists have discovered evidence of multiple ancient mountain ranges beneath Antarctica's ice sheets, including the well-known Transantarctic Mountains and a potentially older range over 500 million years old, using advanced geophysical techniques. These hidden formations play a crucial role in Earth's geological history and influence climate patterns, with ongoing research promising to deepen our understanding of the planet's past.
