Utah mountain hides enough ice to fill about 600 Olympic swimming pools

​Timpanogos Rock Glacier ice discoveryFrom a distance it looks like nothing more than a sprawling pile of rocks high in Utah’s Wasatch Range. But beneath the rubble of Mount Timpanogos is a spectacular hidden reservoir: ice enough to hold some 1.55 million cubic meters of water, which is about 600 Olympic-sized swimming pools. Now, researchers at the University of Utah have mapped this invisible ice using an unusual approach: measuring tiny variations in gravity across the rocky landscape, the university website reports. It’s the Timpanogos Rock Glacier, one of hundreds of rock glaciers in Utah. Unlike normal glaciers, which are large masses of exposed ice and snow, rock glaciers are covered by a thick mantle of loose rock. That rocky exterior is difficult to study, but below it there may
