Room 92C is an interstitial space between the 92A kiva and the eastern Chacoan wall of 92W. It was created with construction of the kiva by the San Juan occupants of Salmon. The space measures 5.5 x 2.3 m. In all, 12 strata were identified in this room including a floor complex and other strata. Seven features were found in 92C including a sealed doorway, two wall niches, and four adobe plugs in the east wall. The doorway indicates that 92C was used to access the 92A kiva. Thus, 92C apparently served an antechamber-like purpose.
