Room 138W is a San Juan period shallow cobble-and-adobe room measuring 2.4 x 2.2 m, located in Salmon's plaza east of the Great Kiva (Room 130W). Seven strata were encountered, including two floors, fill deposits, and early midden deposits. One hearth feature was found within the room. Room 138W was probably built to house a family that could not find space within the main pueblo. It appears to postdate Chacoan construction and use of the site, but lower deposits in the room (138Z) contained Chacoan pottery. The room may have been built during the latter part of the Chacoan period, perhaps 1110-1120, and then continued in use until the late 1100s or 1200s.
