Room 9W is a poorly defined space in the west sector of Salmon Pueblo, built during the San Juan period. It only has one identifiable wall on the south side of the room and its dimensions are unclear. Only one hearth feature was identified. Four stratigraphic units were defined, with one probable floor. The room is tentatively dated as a late San Juan construction (1200 to 1250) of unknown function and was probably associated with Room 8A.
