Una Vida

Una Vida is an archaeological site located in Chaco Canyon, San Juan County, New Mexico, United States. According to tree rings surrounding the site, its construction began around 800 AD, at the same time as Pueblo Bonito, and it is one of the three earliest Chacoan Ancestral Puebloan great houses. Comprising at least two stories and 160 rooms,^[2] it shares an arc or D-shaped design with its contemporaries, Peñasco Blanco and Pueblo Bonito, but has a unique "dog leg" addition made necessary by topography. It is located in one of the canyon's major side drainages, near Gallo Wash, and was massively expanded after 930 AD.^[3]
