- Context
- Locus 1, subfeature 23.06 pit. F-23 was a pit structure that was later remodeled to add F-2, -16, -17. Area was originally interpreted by Root as a dance area. and had mapped 2circular features. F-23 was at the top of Site Stratum II; filled with a single 30-cm thick fill layer interpreted as post occupational sediment that washed in after final abandonment of the ridgetop. Artifacts in fill: small number of plain gray ware, neck-banded sherds, and 1 early white ware, along with flakes, mano and metate frags. and widely scattered isolated human reains. F-23 was square; meas. 5.3 x 5.35 m in dia; prehistorically excavated 30 cm below the surface. Appeared as a typical early P I structure. Four-post roof support system, central hearth, deflector slot, 2 posible sipapus, wall cist, and ventilator system. Unlike others of this period, F-3 was very shallow, only 30 cm deep. Floor was plastered, walls were smoothed. Vent tunnel extended 2.8 m from SE wall (may have also functioned as an entry). Eventually the superstructure was dismantled, floor was smoothed and replastered. Two small post holes were added, near the NW end of the modified ventilator system entry; a small pit along the E wall was also probably assoc. with this later remodeling (sample for 14C is from this pit F-23.06). F-23.06 was a shallow basin at base of structure wall; meas. 50 x 36 cm in dia., 12 cm deep. Artifacts in pit: 4 Zea mays cupules, charcoal, plain grayware sherds, whiteware sherd, 2 perforators, 3 hammerstones, and 1 cottontail tibia. F- 23 is interpreted as being originally a habitation, although more shallow than others that were excavated. Later, the structure's roof was removed, ventilator system was extended--all probably contenporaneous with construction of other features: F-2 surface room, and F-16 and -17. It was then used as an open plaza area integrated into the complex of structures in that part of the hill top designated Activity Area 3. [Note: why would the ventilator system be extended if the area became an open-air plaza?]
