Researchers in Alaska have found the earliest known evidence that Ice Age humans in North America used salmon as a food source, according to a new paper published this week in the Proceedings of the National Academy of Sciences.

The findings counter traditionally held beliefs that Ice Age Paleoindians were primarily big-game hunters. They are based on analysis of 11,500-year-old chum salmon bones found by University of Alaska Fairbanks anthropologist Ben Potter and colleagues at the Upward Sun River site in Interior Alaska. Excavation of the site has revealed human dwellings, tools and human remains, as well as the salmon bones.

“Salmon fishing has deep roots, and we now know that salmon have been consumed by North American humans at least 11,500 years ago,” said lead author Carrin Halffman, a UAF anthropologist who helped analyze the fish bones with co-authors Brian Kemp of Washington State University, Potter and others.
