This is a projectile point — a stone tool shaped into a form that would have been hafted onto a shaft and used as a projectile or cutting implement.

It measured approximately 97 millimeters in length, which places it in the larger size range for this type of tool.

The technology of its manufacture — the specific way it was shaped, the form of its stem, the overall design — links it to what archaeologists call the Western Stemmed Tradition, and specifically to a variant known as a Windust-type or Parman-type point.

The obsidian is significant beyond just the technology.
