Headline: UNCAPTIONED: Archaeologists Uncover 12,000-Year-Old 'Ghost Footprints' In U.S. Air Force Base
Caption: Archaeologists have discovered 12,000-year-old human footprints in a U.S. air base. The 88 human footprints were found at Utah Test and Training Range in Utah's West Desert. The findings have been nicknamed “ghost footprints” because they only become visible after it rains when they become darker in colour after being filled with moisture, before disappearing again once it’s dry. A team of researchers led by Cornell University determined the prints belonged to adults and children who were walking through shallow water during the Ice Age, when the now dry landscape was cloaked in wetlands. The sand in the water quickly filled in their footprints, but mud underneath kept the prints intact. The footprints are believed to be only the second such discovery in the U.S.
