When Jeff Rasic encountered the Trail Creek tooth in the collections in 2016, his recognition of its potential was based on specific knowledge: knowledge of what early Alaskan human remains looked like, knowledge of what sites like Trail Creek had produced, and knowledge of what modern analytical methods could extract from specimens of this type and age.

National Park Service archaeologists working in Alaska have a specific responsibility for the archaeological resources of the lands under NPS management, which include some of the most archaeologically significant areas in the state.

The Bering Land Bridge National Preserve, which protects much of the former Beringian landscape of the Seward Peninsula, is among the most historically significant areas in this region.

Archaeologists working with the Preserve are in a position to recognize the significance of materials from sites within or near its boundaries.
