The NSF- Ice Core Facility has started offering public tours on a limited basis as the spread of COVID-19 has lessened. Tour sizes are being held to 20 people or less once a week. If the CDC tracked transmission levels of COVID-19 in Jefferson County rise into orange, tours will be suspended until levels drop back to yellow or green. For more information about scheduling a tour, visit our Tours and Media page.

When one is already in possession of the world's oldest chunk of ice, perhaps it's only natural to want to go older. John Higgins, a Princeton University assistant professor of geosciences, led a team of researchers who reported in 2015 the recovery of a 1-million-year-old ice core from the remote Allan Hills of Antarctica, the oldest ice ever recorded by scientists.
