- Context
- Room 1, excavated into the fill of the pit house, ca. 1.25 m above the floor of the pithouse. Sample is from a burned post. Interpreted as possibly representing a Late Anasazi/post-Anasazi ramada. However, the radiocarbon date of AD 440 +/- 140 is inconsistent with this interpretation and has correctly been rejected by the author. (I recalculated the date into a BP date, assuming that the AD 440 date was uncalibrated. Thus the date in the database may be incorrect.)
