Scientists discover nearly 1 billion tons of water locked inside Utah's rocky glaciers, using gravity measurements to map ice buried beneath mountain debris

At first glance, Utah’s rocky mountain slopes may look completely dry, with loose stones and boulders covering the ground. But beneath some of those rocks lies an enormous store of frozen water. Researchers have now estimated that Utah’s rock glaciers contain about 0.99 gigatonnes, or nearly 1 billion tons, of water equivalent. These unusual formations … Read more

Icebergs in Antarctica (Image Credit: Canva) Antarctica may look like a vast, frozen and unchanging landscape, but deep beneath its thick ice lies a surprisingly active world. In 2007, scientists reported findings based on measurements collected by NASA’s ICESat satellite between 2003 and 2006, revealing major changes in the surface of the West Antarctic Ice … Read more
