Scientists have uncovered a massive ice reservoir beneath Mount Timpanogos in Utah, containing enough frozen water to fill 600 Olympic-sized swimming pools. The discovery was made using gravity measurements that mapped the buried glacier in three dimensions.

Rock glaciers form when falling debris buries persistent snow and preserves it for thousands of years. This hidden ice could play a crucial role in understanding regional water resources and climate impacts.

Similar formations worldwide may collectively store tens of gigatons of hidden water, highlighting the need to further investigate these underground reservoirs to assess their potential impact on local ecosystems and water supplies.
