- Context
- thermal refuse in Pit Structure Feature 3. Situated on the floor immediately E of the deflector. Consisted of a refuse pile of material apparently cleaned out from the hearth. Structure was sub-rectangular oriented ESE. Subfeatures: a full bench, 4 main support postholes, a wingwall and 22 subfeatures excavated into the floor. The latter included 2 bell-shaped storage pits, a ventilator opening (bifurcated), 2 slab lined bins, 2 sipapus, a central hearth, and other pits. Very few floor contact artifacts, some bone (including black bear), a few grayware and Rosa/Piedra whiteware sherds, 2 flakes, and 6 manos. Interpreted as indicating a planned abandonment. Fill was mostly derived from the excavation of Feature 45, a nearby pit structure. Also contained two later episodes of trash deposition.
