In 2002, a team of researchers from Oregon State University found evidence of human presence on the southern Oregon coast at the Indian Sands area of Boardman State Park dating more than 10,000 years ago — more than 2,000 years older than previously known archaeological sites on Oregon's coast. Carbon dating of artifacts (similar to ones found on the Alaskan and British
Columbia coasts) suggested an origin approximately 12,000 years ago.[3][4][5]
