 Chaco Road is a network of roads (for travel and trade) which radiated from great house sites, such as Pueblo Bonito, Chetro Ketl and Una Vida, leading to small house sites on the periphery of Chaco Canyon.Una Vida today is in a near-natural state of preservation, with minor excavations.A one-mile roundtrip trail is now in place so that tourists can come and explore the site as they please.
