Este es el contexto:
Prior to excavation it was unclear if these areas were very large roasting features, trash middens, or structures of melted adobe and stone. A trench .5 by 4 m was excavated north south through the feature, but did not extend beyond its borders in either direction. The feature was excavated in .10 m levels to a total depth of approximately .37 mbgs (Figure 31 and 32).
