 Subsequent use by local Middle San Juan people (beginning in the 1120s) resulted in extensive modifications to the original building, with the reuse of hundreds of rooms, division of many of the original large, Chacoan rooms into smaller rooms, and emplacement of more than 20 small kivas into pueblo rooms and plaza areas.The site was occupied by ancient Ancestral Puebloans until the 1280s, when much of the site was destroyed by fire and abandoned (Reed 2006b).The pueblo is situated on the north bank of the San Juan River, just to the west of the modern town of Bloomfield, New Mexico, and about north of Pueblo Bonito in Chaco Canyon.
