Room 140W was probably constructed towards the end of the Chacoan period at Salmon Pueblo. It was built as an addition to the Chacoan roomblock just west of Room 68W. The room measures 2.2 x 2.2. No work was completed beyond exposing walls and no features were recorded. A single stratum was defined. There are no feature, strata, photographic, or documentary records available for this room.
