Central hearth or firepit in Hank's house before it was excavated. The layers are: (A) upper fill, post-occupation deposits; (B) layer of burned branches and clay daub from roof fall; (C) blow sand inside hearth; (D) ash layer at bottom of hearth; (E) baked clay lining of the hearth; (F) pre-house sandy soil into which the house was dug; and (G) caliche rocks that are part of a natural layer of intermittent gravel in the alluvial terrace (i.e., representing a flood event before the house existed).
