Between AD 300 and 1300 in the northern part of the state along the wide, fertile valley on the San Miguel River the Casas Grandes (Big Houses) culture developed into an advanced civilization. The Casas Grandes civilization is part of a major prehistoric archaeological culture known as Mogollon which is related to the Ancestral Pueblo culture. Paquime was the center of the Casas Grandes civilization. Extensive archaeological evidence shows commerce, agriculture, and hunting at Paquime and Cuarenta Casas (Forty Houses).
