Buried 2 miles beneath Antarctica's ice, a colossal hidden structure may rewrite its history

Scientists have discovered a massive hidden geological structure beneath the East Antarctic Ice Sheet. The East Antarctic Fan-Shaped Basin Province connects various sub-glacial features, including Lake Vostok, and may impact how the overlying ice responds to the underlying terrain. Researchers mapped the province through a combination of geological observations, gravity readings, and models of the crust, determining that the buried formation likely formed over millions of years through continental crust stretching outward. This finding could aid studies of massive ice sheets responding to global temperature changes.
