Room 142W 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 62W. The room measures 4.4 x 2.5. No work was completed beyond exposing walls. Two doorway features were noted and one stratum was defined. There are no feature, strata, photographic, or documentary records available for this room.
