Room 84W is an original Chacoan room located in the second tier of rooms from Salmon's north wall. It measures 5.7 x 2.9 m. Fourteen strata were identified in the room, including a mix of Chacoan and San Juan deposits. One San Juan period roof-fall strata was recorded. The remaining deposits in the room were of Chacoan origin, including a floor, trash and occupational layers, feature specific strata, and a number of strata related to the room's construction. Eight features were associated with Rooms 84W including doorways in the north and south walls, vent windows, a storage pit and a trash pit. Given these findings and the room's location, a storage function seems likely. Tree-ring dates indicate construction around 1090.
