The event predates the Clovis horizon by several hundred to approximately 900 years.

The evidence provides direct physical documentation of pre-Clovis mastodon hunting in the Pacific Northwest.

These conclusions are well-established.

They rest on multiple independent lines of evidence — radiocarbon dates, high-resolution CT imaging, protein analysis, 3D digital reconstruction — that converge on the same interpretation.

But significant questions remain, and they remain not because the investigation was inadequate but because the evidence that survived is limited.

A single rib, a few embedded fragments, a reconstructed tip — these are all that chance preserved from an event that lasted, at most, a few hours.
