Context
A pit house (Feature 10) was exposed one meter below the recently graded ground surface in the trench wall lying on top of Pleistocene deposits. In cross-section, the pit house (Figure 11) appears as a large, lenticular charcoal stain containing interior hearths or possible storage cists. It measures 6 meters in diameter and 20-40cm in depth. The stratigraphic position and approximate size of the pit house suggested a Middle Archaic affiliation.
