As geologists look at the map created from data they’ve collected in Yellowstone National Park, one thing is clear. They’ve uncovered something incredibly unsettling below the Earth’s surface. The danger it poses could be world-changing, in fact. And it’s happening right beneath one of America’s most treasured attractions.
The researchers, from Britain’s Royal Holloway University, were interested in finding out what’s going on far below the surface of the Earth. Studying the planet’s depths, however, is no easy task. The researchers needed to get to the layer called the “upper mantle,” hundreds of miles beneath ground level. And this is a job that requires special equipment.
