Room 57W is an original Chacoan room located in the central section of Salmon Pueblo, east of the Tower Kiva (Room 64W). It measures 5.5 x 3.2 m. Twenty strata were identified in Room 57W. The upper strata were San Juan era in origin, consisting of roof-fall layers. The middle strata were mixed roof-fall strata with Chacoan and San Juan ceramics. The lowest strata were fill units with Chacoan ceramics and construction materials. Few artifacts were recovered from any of the strata in 57W. Sixty-four features were identified in Room 57W, the majority being latillas, vigas, and their respective wall sockets. Other features included doorways, a niche, five hearths, and a ladder made of stone. This ladder construction is unique to Salmon Pueblo, and provided access to a second-story doorway into Room 58W. Room 57W probably served a habitation or living function.
