More than a dozen dwelling, ritual and funerary sites, some of them more than 1,000 years old, were located inside shallow caves at Barranca de la Sinforosa (Sinforosa Gully), Chihuahua. According to preliminary studies, vestiges could correspond to Tubar people, an indigenous group that isolated in Tarahumara Mountain Range during Colonial times to avoid evangelization, and extinguished in late 19th century.

Nine dwelling sites, 2 ceremonial and 2 of funerary character were found in Ohuivo, Chorogue, Zapuri and Güerachi localities of Guachochi municipality in Chihuahua.

Archaeologist Enrique Chacon, from the National Institute of Anthropology and History (INAH), declared that according to first explorations, 3 types of sites were identified, which, according to architecture, burial system and regional research references, are dated in 16th-17th centuries, while others could go back to 11th century of the Common Era.
