The Chihuahua (Southeastern) tradition (ca. 6000 BC to ca. AD 250) as a culture of south-central New Mexico and Chihuahua is still poorly defined. It probably includes several local adaptations that evolved over long periods of time. Irwin-Williams' hypothesis of four interacting Southwestern Archaic traditions, which differ from other traditions such as the Plains Archaic, is still provisional.
