Altavista, or Chalchihuites, is an archaeological site near the municipality of Chalchihuites in the Mexican state of Zacatecas, in the northwest of Mexico. It is believed that the site was a cultural oasis that was occupied more or less continuously from AD 100 to AD 1400. The site is within the "Sierra de Chalchihuites" – from the Nahuatl word chalchíhuitl, the name means "precious stone" – where the Chalchihuites-Chichimec culture was established.
