Room 102D is the eastern subdivided portion of 102A. Ten Chacoan strata were identified in the room. No floor was found; the strata consisted of trash deposits, artificial fill layers, and feature-specific strata. Artifacts were found in all strata. Room 102D had four Chacoan age features: three postholes and a pit of unknown function. The room's original function is unclear but it was used as a trash-dumping area in the late Chacoan and San Juan periods.
