Statement of Significance (as of designation - April 29, 1964):
Excavations at Snaketown by Gila Pueblo revealed that the Hohokam of southern Arizona were strongly influenced by the more highly developed cultures of Mexico, particularly between AD 500 or 600 and 1150, and later. Not only did these excavations definitely establihs the Hohokam as one of the main culture groups of the Southwest, but als demonstrated the chronological development that took place. The introductions from Mexioc lifted the Hohokam into a new pattern of living, which conrasted sharply with the scattered rancherias of the early Indian farmers of this region. Some of the new ideas spread north and east to the Anasazi and Mogollon cultures of Arizona. The extensive irrigation canal system and the large urban developments of "city states" of the late prehistoric period mark the higest achievement of Hohokam labor.
