Eight strata were identified during excavation of the kiva including post-occupational fill units: structured trash, a floor, and a feature stratum associated with the hearth. Twenty features were identified in the kiva including six pilasters, an encircling bench, a southern recess, ventilator shaft, deflector, a hearth, and niche set into the kiva wall.
