Structure 602, kiva, type unknown
About this Structure
Block 600, central part of site, between Blocks 500, 900, and 1500 to the west and the main site drainage to the east.
Northern half of Block 600; immediately east-southeast of the D-shaped building (Block 1500).
This structure contains features typical of Pueblo III kivas in this region. The presence of a prepared floor, masonry bench face, pilaster (collapsed), deflector slab (fallen), and a ventilator tunnel opening indicates that this structure fits our architectural definition of a kiva. Thus, it is inferred that this structure was probably used in the same ways that other ordinary-size kivas in this area were used during Pueblo III times (in general, for domestic purposes and household-level rituals). A few flakes, sherds, and nonhuman bones were associated with the use of the structure within the area of our test pit.
It is difficult to assess the mode of abandonment from the limited data available. From the small area of architecture exposed, it appears that some of the materials from the walls of this structure might have been salvaged. The presence of human skeletal remains (of a person thought not to have been formally buried) beneath burned roof fall is similar to evidence found in several structures in nearby architectural blocks (Blocks 100 and 1000); the evidence indicates that those individuals died in a warfare event that ended the occupation of those kiva suites, and perhaps the village as a whole. If the individual whose remains are on the floor of Structure 602 also died in this event, then this structure was probably abandoned sometime after A.D. 1277 (the latest tree-ring date for the site), as a result of this warfare event. The remains were partly on top of a fallen slab that was inferred to have been the deflector originally, and beneath a series of pecked blocks inferred to have been Pilaster 1 originally. Thus, it appears that the deflector slab was toppled, then the remains were deposited, then the pilaster collapsed (fracturing the fibula), and then the burning or burned roof collapsed. The pilaster was probably knocked down by the collapsing roof.
After the burned roof collapsed, the upper walls collapsed into the depression and additional sediment was deposited naturally. Sometime during structural collapse, the surface of the southern recess caved in, into the ventilator tunnel.
