Chaco Culture National Historical Park

Pueblo Bonito is the largest Chacoan Great House in Chaco Canyon. Occupied from 850 AD until the 1250's, it was four and five stories high with over 600 rooms, and covered three acres.

Chaco Culture National Historical Park is located in a rugged canyon in northwestern New Mexico. For around 500 years it was the center of Ancestral Puebloan culture and trade. Massive pueblo structures were built, and over 400 miles of roads connected Chaco Canyon with outlying communities. The peoples eventually moved on, and the ruined remains of many of these pueblos are preserved by the National Park Service.
