Which Indigenous peoples found refuge in the Sierra Madre mountains?

The rugged terrain, remoteness, and relative inaccessibility of the Sierra Madre mountain system have historically served as a refuge for various Indigenous peoples, allowing them to retain much of their traditional culture for centuries following initial contact with the Spanish.12

Key groups that found refuge in these mountains include:

• Tarahumara (Rarámuri): Located primarily in the northern state of Chihuahua.12
• Huichol and Cora: Inhabiting the plateaus and gorges of the Sierra Madre in the southern states of Nayarit and Jalisco.123
• Other groups: Various Indigenous populations also sought refuge in the Sierra Madre del Sur, as well as specific groups such as the Pima Bajo along the Sonora-Chihuahua border and the Tepehuan in the sierras of southern Durango, Nayarit, and Zacatecas.12

While these mountains provided a sanctuary that helped preserve traditional languages, clothing, and social structures, many of these groups have faced gradual acculturation to the Mexican mestizo way of life, a process accelerated by 20th and 21st-century technological advancements.12
