The specific forms of these points — their size, their shape, the details of how their stems are constructed, the technology used to produce them — connect them to the broader Early Archaic tradition of the southern Plains and Gulf Coastal Plain.

But some artifacts found in Early Archaic Texas contexts are made from materials that are not local.

Obsidian — volcanic glass, whose sources are located primarily in the Trans-Pecos mountains of far west Texas, in New Mexico, and in places even farther afield — appears occasionally in Early Archaic assemblages from the Edwards Plateau and coastal plain.

Its presence documents the same long-distance connections that the marine shells document: contacts with groups far from the immediate territory.

The technology of Early Archaic tool-making was not static.
