The 13,900-Year-Old Mastodon Rib Found With A Bone Point Still Inside — And The CT Scan That Put Hunters Before Clovis
Gustafson had been conducting regional surveys of the Olympic Peninsula and the broader Puget Lowland for years, familiar with the area’s prehistoric potential and positioned to recognize the significance of what Manis had found.
Gustafson excavated the site over multiple seasons beginning in 1977.
The work was careful and systematic — the kind of fieldwork that produces the documentation on which later researchers depend.
He identified the mastodon skeleton, characterized the associated materials, and noted the unusual rib with its embedded object.
He made the interpretation that the embedded fragments were a projectile point, documented his reasoning, and published his findings.
Then he waited.
