General description
Burned slab-walled pit on extramural surface.
Use history
Pit was excavated into undisturbed sterile sediments, except for the western edge, which may have truncated the east edge of a midden deposit. Pit was used to contain fire for some unknown purpose (cooking, food processing etc.). No evidence of use-type found in fill during excavation, except for a few burned faunal remains.
Associated features
None.
Excavation procedure
Bisected length of feature; excavated east half, then west half in a full cut.
Horizontal location
Crosses the northeastern portion of 2-x-2 m unit 657N 379E; in 1100 roomblock midden area.
Vertical location
25-30 cm below modern ground surface at the base of plow zone; top of undisturbed soil.
Construction
A rectangular pit was excavated into sterile deposits; pit walls were lined with upright slabs. Bottom of pit was flat except for two round pits (30 cm diameter) excavated into the floor; sandstone slabs were set into each of these pits (see map #121). Adobe was used in front of and around the slabs.
Remodeling/ modification
Yes. No evidence.
Thermal alteration
Yes. Walls and edges of the floor were heavily oxidized; floor and floor slabs were heavily charred.
Sooting
Yes. Could be possible with the charring; soil was too damp to tell.
Degree of preservation
