PORTLAND, Ore. (KOIN) — Oregon State Scientists and students have uncovered some of the oldest artifacts ever found in North America.
They’ve been working at a Nez Perce Tribe site in Cooper’s Ferry, Idaho, for the last decade.
The crews recently uncovered artifacts dating back 16,000 years.
The discovery challenges one theory that the native people of the Pacific Northwest crossed from Siberia on an ice passage.
The artifacts pre-date the time they would have been able to cross. Oregon State researches believe this shows people were already here.
The oldest artifacts include stone tools, a hearth and food processing station.
