Archeologists believe that today's Pueblo people descended from groups of hunters and gatherers who came to northern New Mexico over 10,000 years ago. These Ancestral Pueblo People were farmers, weavers, and potters. By the mid-1200s some of the communities were made up of villages of as many as 40 rooms. The Long House at Bandelier is an 800 foot stretch of adjoing, multistoried stone homes with hand-carved caves as back rooms. The ruins at Bandelier include many homes with cave extensions, as well as kivas (round, underground caves that were the center of religious life), petroglyphs, footpaths, and the spirits of those Ancient peoples who came before today's Pueblo People. By the mid-1500s villagers had moved on, settling into new homes in villages along the Rio Grande River. Descendents of this group continue to live in several Pueblos in the region of the Frijole Valley.
