Room 101W is an original Chacoan room located in the second row of rooms from the back wall in the northeastern section of Salmon Pueblo. It measures 5.7 x 2.9 m. Eighteen strata were identified in 101W, including post occupational fill and San Juan and Chacoan age deposits. The San Juan era strata consisted of roof-fall, fill, and structured trash. Chacoan strata included a floor complex, occupational fill, structured trash, and feature related deposits. A total of 13 features, all Chacoan in origin, was recorded in Room 101W. Chacoan features consisted of roof-related features, hearths, a slab feature, and a storage pit. These features support the idea that 101W was used for a habitation function. Tree-ring dates indicate that 101W was built during the initial Chacoan occupation around 1090 and subsequently used by the San Juan inhabitants.
