The Anasazi (Hisatsinom) lived much longer at Canyon de Chelly, also located on the Navajo Reservation. There are over 700 prehistoric sites here, including Whitehouse Ruins, Antelope House, Mummy Cave Ruin, and others. The Anasazi (Hisatsinom) built these cliff dwellings between 1100-1300 C.E.. When the Ansazi left, the Hopi and Navajo later occupied the site. Canyon de Chelly became a national monument in 1931, and is on over 130 square miles of land now owned by the Navajo. The Anasazi (Hisatsinom) also lived in the region now known as the Petrified Forest National Park and, although they did not know what petrified wood was, they used it to build their dwellings. They lived here from 1050 B.C.E. to 1400 C.E.

As the Anasazi (Hisatsinom) abandoned their cliff dwellings here, they joined other tribes in the area. For example, one group of Anasazi (Hisatsinom) joined the inhabitants of Pecos somewhere around the twelfth century and began to build their multi-story pueblos. Pecos was an important center of trade between the Pueblo and Plains Indians. The Spanish conquistadors first arrived in the 1540s, and in 1598 Spanish missions were established in Pecos to convert the Native Americans to Christianity. The remains of the largest mission church built in 1625 can still be seen under later structures. The Pueblo Indians destroyed the mission in 1680 and drove the Spanish south to El Paso, Texas. The Pecos Anasazi (Hisatsinom) recovered their native traditions and built a kiva in the ruins of the Spanish church. In 1692 the Spanish regained control of Pecos and New Mexico, ending a long era of Anasazi occupation.
