Aftonian The earliest (1.3–0.9 Ma) of four interglacial stages in North America, following the Nebraskan glacial episode, and approximately equivalent to the Donau/Günz interglacial of Alpine terminology. Climatically it was marked by mild summers and winters warmer than those in present-day North America.
