The deposit hidden within the McDermitt Caldera is estimated to hold between 20 million and 40 million metric tons, which would be nearly double the current record of about 23 million metric tons found over the summer beneath a Bolivian salt flat, researchers reported in Science Advances. It would also greatly boost...
