Overview
After Chaco's decline, the focus of Ancestral Puebloan regional organization shifted north to the Totah area at the confluence of the San Juan and Animas rivers in northwestern New Mexico — the "Aztec" regional system, named for the great houses at Aztec Ruins (a misnomer coined by 19th-century Anglo settlers who wrongly credited the Aztecs of Mexico; the builders were Ancestral Puebloans). The principal sites are the Aztec Ruins great houses (Aztec West, with its famous reconstructed Great Kiva) and the nearby Salmon Ruins on the San Juan.
History
This "post-Chaco" system, flourishing roughly 1110–1275, replicated Chacoan great-house architecture, planned layouts, and ceremonial kivas, and is often interpreted as a deliberate attempt to relocate the "Chaco center" northward to better-watered land as the San Juan Basin dried out. It maintained the Chacoan tradition for another century or so before it too was abandoned.
Decline and legacy
The 13th century brought the Great Drought (c. 1276–1299) and broader environmental and social stress that triggered the wholesale Ancestral Puebloan migration — the depopulation of the Four Corners region (including the cliff dwellings of Mesa Verde) by around 1300. The people did not vanish; they moved south and east to form the historic Pueblo communities along the Rio Grande and at Hopi and Zuni, carrying forward their architecture, agriculture, and religion. The abandonment of the Four Corners is one of the most studied episodes in North American archaeology, with drought, resource depletion, warfare, and ideological/religious reorganization all cited as contributing causes.
