Archaeologists chanced upon ancient tracks while driving to a hearth site in Utah. With the help of radar, they uncovered 88 footprints of adults and children who appear to have been walking in shallow water. The area hasn’t been wetland for at least 10,000 years, and the researchers estimate that the footprints are 12,000 years old, but more research needs to be done. Interestingly, one of the nearby hearth sites is where the oldest evidence of tobacco use was found. I’m excited to hear more — reliable dating could have big implications in the debate about the age of the White Sands footprints.
