A Mesoamerican 'frontier' or 'transition' culture along the eastern flank of the Sierra Madre Occidental, spreading through a corridor from western Zacatecas to Durango and marking the northernmost extension of Mesoamerican urbanism into the arid Chichimec-inhabited plateau (per archaeologist Manuel Gamio's classification). Its principal ceremonial center, Alta Vista (near the modern town of Chalchihuites), had a hieroglyphic writing tradition, planned ceremonial architecture, and controlled a turquoise-trade corridor originating in the oasis-American mines of New Mexico; cultural florescence peaked roughly AD 400-650.
Population and monumental building at Alta Vista and related centers declined after c. AD 800 following a severe regional dry spell that devastated farming in the semi-desert; the wider Chalchihuites tradition (including its later Suchil/Guadiana-area successors) faded out by roughly the 13th century as Mesoamerica's northern frontier contracted southward ahead of the Postclassic era.
