Room 92A is the San Juan period kiva emplaced in Chacoan Room 92W in the post-Chacoan period. The structure measures 4.4 m in diameter and its construction created interstitial spaces (92B–F) around it between the kiva and room walls. Seventeen strata were identified in the 92A kiva including trash and a floor layer. Sixteen features were associated with the kiva, many of which are typical of San Juan kiva features. These included a central hearth, deflector, ventilator shaft and tunnel, a southern recess, and a round structural wall. In contrast, the kiva lacks features found in other kivas at the site, such as pilasters, a bench, and a sipapu. Architecture and ceramics indicate construction in the late mid-1100s or early 1200s.
