Scientists Mapped a Hidden Glacier Using Gravity

Though it’s hidden, the glacier contains an enormous amount of ice: 1,550,000 cubic meters, or enough to fill Egypt’s largest pyramid, according to a new study published in the Journal of Geophysical Research: Earth Surface. The study provides a detailed 3D map of the rock glacier using a new approach and is an important step toward a better understanding of rock glaciers in Utah and beyond, said Doug Clark, a geologist at Western Washington University who was not involved in the study but researches rock glaciers in the western United States and New Zealand.
