During the postclassical period the city was occupied by Zacatecas people and their contemporaries tepehuanos, from the southeast of the Guadiana Valley up to “Nombre de Dios”.

[2] La Ferrería was first inhabited by a group that basically subsisted from farming corn, beans and squash, and were hunter-gatherers to complete their diet; because of its proximity to the Tunal river, it is assumed that hunting and fishing were common activities.

[6] This broad area represents the natural corridor that the Sierra Madre Occidental offered to the Toltec and Nahuatlaca tribes, both of whom took advantage of the large accidental stone conformations to survive in the wilderness of the territory.

The Huichol, Cora, and Tarahumara Tepehuanos incorporated perfectly distinct nations, each with evident sedentary purposes, and a strong family structure, all whilst setting aside the bellicose attitude of the Chichimec tribe of the center of the then-current Republic.

The "Indios Laguneros" (Laguna Indians) traveled interchangeably between this area, they were characterized by their rebellious attitude, instability, religious customs and for being hunters and gatherers.

Although agricultural techniques were imported from the south, Oasisamerican villages built a civilization with particular characteristics, that maintained relations with Mesoamerica farmers.

In the following decades, especially under the command of Francisco de Ibarra, several settlements were founded in the territory and further north of the city of Zacatecas, when silver deposits were discovered.

Nueva Vizcaya included the current states of Chihuahua and Durango, as well as certain areas of eastern Sonora and Sinaloa and southeast of Coahuila.

The first scientific news on this site was in 1948, by American anthropologist Alden Mason; four years later Charles Kelley, with a group of students from University of Chicago, started initial research work, from which he removed multiple archaeological pieces and prepared three essays.

[9] After Kelley research, the site was abandoned by the authorities for 40 years, with the consequent destruction and looting by professional dealers of archaeological pieces.

[4] There are important archaeological complexes, among them: circular ritual spaces, eastern pyramidal structure, ballgame court, columns and sunken patios.

[10] There are two large engraved rocks: One of them depicts a small image that represents a priest with the arms high and wears a ceremonial ornament with antlers.

The rock was partially polished and is the focal point of a small area dedicated to the cult, may be considered the place of protective deities.
