Guila Naquitz, a small microband camp, did not contain the full range of tools known for the preceramic; no one site of that period did. There is also at least one low ignimbrite mesa in the area that seems to have been used as a quarry for silicified material.

Most of us probably implicitly attribute the rapid disappearance of aboriginal stone-working traditions after European contact to the quick recognition by native groups of the technical superiority of metal tools, and, possibly because of this assumption, this disappearance is not often a research domain in itself.
