In a recent study, University of British Columbia researchers surveyed those deposits at the Kima’ Kho tuya, which erupted under an ice sheet about 1.8 million years ago. Their findings suggest that he ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated. Continue reading
