|Salmon Ruins National Monument
|Salmon Ruins is an ancient Chacoan and Pueblo site located in the northwest corner of New Mexico, USA. Salmon was constructed by migrants from Chaco Canyon around 1090 CE, with 275 to 300 original rooms spread across three stories, an elevated tower kiva in its central portion, and a great kiva in its plaza. 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 1280.
