The 13 “razor sharp” stones are considered some of the oldest weapons discovered in North America, dating back nearly 16,000 years.
Similar stone points found at the same site, on traditional Nez Percé land, are still about 2,300 years younger than this latest cache of weapon heads.
“These discoveries add very important details about what the archaeological record of the earliest peoples of the Americas looks like,” said Oregon State University professor“It’s one thing to say, ‘We think that people were here in the Americas 16,000 years ago.’ It’s another thing to measure it by finding well-made artifacts they left behind,” added Davis, whose research previously identified tool fragments and pieces of bone from the same era.
All told, the team’s excavation at Cooper’s Ferry, near the Salmon River, has uncovered over 65,000 artifacts. The finely honed darts are also strikingly similar to those seen in Hokkaido, Japan, dating from 16,000 to 20,000 years ago, Davis noted — adding intrigue to the hypothesis that ice age peoples of North America and Northeast Asia met much sooner than we can yet prove.
“By comparing these points with other sites of the same age and older, we can infer the spatial extents of social networks where this technological knowledge was shared between peoples,” said Davis.
