The 124Z designation was used to track features and deposits from an occupation earlier than the Chacoan use of Room 124W. These remains were found below the earliest Chacoan floor and extended beneath the walls of the room and the later San Juan kiva. Twenty-four strata were found including surfaces, pre-Chacoan deposits, and numerous feature-related strata. Twenty-five features were identified in 124Z including hearths, a bin, storage pits, roasting pits, postholes, cists, a burial, and walls. This diversity supports the concept of an earlier, pre-1090 occupation underlying the southeast sector of Salmon Pueblo. Tree-ring dates suggest a range of 1068-1072.
