The site called Amigo West (AW) es of great importance in the region. In this hill was found a lithic assemblage composed of more than one hundred fishtail points (FTP), vifaces, knives and marginally retouched tools, and a large numbers of others artifacts that correspond to the sequences of manufacturing, ractivation, recycling and replacement of the FTP.
