Mogollon cultureMogollon culture (ˌmoʊɡəˈjoʊn) is an archaeological culture of Native American peoples from Southern New Mexico and Arizona, Northern Sonora and Chihuahua, and Western Texas. The northern part of this region is Oasisamerica, while the southern span of the Mogollon culture is known as Aridoamerica. The Mogollon culture is one of the major prehistoric Southwestern cultural divisions of the Southwestern United States and Northern Mexico. The culture flourished from the archaic period, 200 CE, to either 1450 or 1540 CE, when the Spanish arrived.
CoahuilaCoahuila (koaˈwila), formally Coahuila de Zaragoza (koaˈwila ðe saɾaˈɣosa), officially the Free and Sovereign State of Coahuila de Zaragoza (Estado Libre y Soberano de Coahuila de Zaragoza), is one of the 32 states of Mexico. Coahuila borders the Mexican states of Nuevo León to the east, Zacatecas to the south, and Durango and Chihuahua to the west. To the north, Coahuila accounts for a stretch of the Mexico–United States border, adjacent to the U.S. state of Texas along the course of the Rio Grande (Río Bravo del Norte).
Opata peopleThe Opata (Ópata, /ˈopata/) are an indigenous people in Mexico. Opata territory, the “Opatería” in Spanish, encompasses the mountainous northeast and central part of the state of Sonora, extending to near the border with the United States. Historically, they included several subtribes, including the Eudeve, Teguima, and Jova peoples. Most Opatan towns were situated in river valleys and had an economy based on irrigated agriculture. They spoke the Opata language, a Uto-Aztecan language, that is now extinct.
Sky islandSky islands are isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau, and has extended to similarly isolated high-elevation forests. The isolation has significant implications for these natural habitats. The American Southwest region began warming up between 20,000 and 10,000 years BP and atmospheric temperatures increased substantially, resulting in the formation of vast deserts that isolated the sky islands.
Southern Athabaskan languagesSouthern Athabaskan (also Apachean) is a subfamily of Athabaskan languages spoken primarily in the Southwestern United States (including Arizona, New Mexico, Colorado, and Utah) with two outliers in Oklahoma and Texas. The language is spoken to a much lesser degree in the northern Mexican states of Sonora, Chihuahua, Durango, Coahuila, and Nuevo León. Those languages are spoken by various groups of Apache and Navajo peoples. Elsewhere, Athabaskan is spoken by many indigenous groups of peoples in Alaska, Canada, Oregon and northern California.
