Context: AMS date from Feature 2, a pit structure. Sample is from the floor (NOTE: other dates from what was thought to be roof fall are much later and are not assoc. with use of the structure. First identified in a pipeline trench. Unburned, oval, semisubterranean to subterranean; bisected by the trench which ran exactly through the center removing the central 70 cm. Bowl-shaped in profile because the walls flare outward. Top of structure was 26- 16 cm bmgs. It meas. 2.75 x 3.6 m in dia. at the top of the walls, but only 2.15 x 2.8 cm at the floor. Depth is 65 cm. Walls were unprepared. Other than leveling, floor was leveled and use packed; very even. Only 1 floor feature: 1 posthole, 14 x 13 cm in dia. 22 cm deep; located near the SW wall. Floor artifacts: 1 core, a mano, and 2 small tabular slabs. A thin layer of water deposited sediments was just above the floor. Fill was mostly a very compact silt loam that was difficult to distinguish from the surrounding sediments. The absence of ceramics and the morphology suggested that it might be BM II/Late Archaic. The lack of substantial floor staining suggests that the structure was only temporarily occupied. Two later pits, Features 1 and 4, were partially excavated into the fill of the pit structure, and likely account for the more recent dates in the fill of the structure.
