Reconstructed walls from the ancient pueblo at Aztec
Reconstructed pueblo walls

These well-preserved ruins comprise the Aztec Ruins National Monument: structures and artifacts of Ancestral Pueblo people from the 1100 and 1200s. People associated with Chaco Canyon to the southeast built and used the structures before abandoning the area during the Great Drought of the late 1200's.

Sometime in the late 1000's, a group of Ancestral Puebloans planned and began building a large community on high ground overlooking the Animas River. 200 years later, the complex they had originally designed had grown into several great houses, some small residential pueblos, tri-walled kivas, roads, earthworks and a great kiva. When you consider the formal layout of the settlement, the purposeful modifications of the landscape and the orientation and visual relationships among the buildings, you can see that the final product was visualized in the original design and finished several generations after the original designers passed on.

In the early 1100's, the great house of the West Ruin was built. This structure consisted of at least 400 contiguous rooms with three stories and numerous kivas, including a great kiva in the plaza.

By 1130, the majority of construction activity shifted to the area of the East Ruin (which area is presently off-limits to the public). Another 150 years was spent in the construction of the East Ruin. Both of these ruins were built in Classic Chacoan style although both structures were built as Chaco was being abandoned. By about 1150 CE the ruins at Aztec had become the new Chacoan capitol.

Archaeologists figure the Aztec Ruins were pretty much abandoned by the late 1200's as the growing drought forced the people either west into Arizona or east to the Pajarito Plateau before moving to the Rio Grande in New Mexico in search of water and better living conditions.
