Abstract
Many distal tephra beds exist in the thick, fossiliferous loess deposits near Fairbanks interior Alaska. Isothermal plateau fission-track ages, determined on glass shards from tephra beds, in conjunction with tephrostratigraphic and magnetostratigraphic techniques, indicate that loess deposition began in the late Pliocene-an antiquity previously unsuspected. Hence, there is the opportunity now to reconstruct a detailed, well-dated record of environmental changes in interior Alaska during the past 3 m.y.
