The Iyatayet Site is an archaeological site and National Historic Landmark located on the northwest shore of Cape Denbigh on Norton Bay in Nome Census Area, Alaska. It shows evidence of several separate cultures, dating back as far as 6000 B.C. It was excavated starting in 1948 by J. Louis Giddings, the pioneering archaeologist of the area. It is significant as the type site of the Norton culture, representative of human occupation c. 500BCE-500CE, first described by Giddings in 1964. It is also significant for the Cape Denbigh Flint Complex, which lay underneath the Norton materials, and provides evidence of some of the earliest human activity in the region. The site was declared a National Historic Landmark in 1961.
