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 exceptions were the Acaxee, Humas, and Xiximes who were constantly at war but always on the look-out for final settlements in the region of the Quebradas. On the east bank of the state a longitudinal zone can be found, that extends from the current state of Zacatecas to the la Laguna area between the entities of Durango and Coahuila. 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. These Natives of which so little was recorded were the first inhabitants of the region long before they were exterminated by the Spanish colonists. Today, only a few remain of the Tepehuanos, Huicholes, Coras and Tarahumara tribes. There is an opinion which assumes that Mesoamerican cultures would have migrated northward. Hence Oasisamerica would be a branch of neighboring southerners. In that regard, the development of Oasisamerican cultures, such as those from northern Mesoamerica, would have been related to groups originally inhabiting western Mexico. Archaeological evidence suggests an affiliation with uto-nahua groups would have taken agriculture to the Oasisamerican region. Although agricultural techniques were imported from the south, Oasisamerican villages built a civilization with particular characteristics, that maintained relations with Mesoamerica farmers. One must remember that Durango is at the south border of the Mogollon – Anasazi cultures influence area. Site investigation Spanish exploration began in 1531 with the Nuño de Guzmán expedition. 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. Ibarra named the new area Nueva Vizcaya in honor of his native land Biscay (one of the Basque historical territories). 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 region fell under the legal jurisdiction of the “Royal Guadalajara Audiencia”. 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. The final disposition of archaeological material is
