Today the Northern Tepehuan are closer to the Tarahumara cultural pattern than to that of the Southern Tepehuan, and relations with the Tarahumara are plainly evident. In a few communities, the two groups live together in bicultural and bilingual situations, but the precise relationship between them is unclear. The Northern Tepehuan are found in the municipios of Guadalupe y Calvo, Morelos, and Balleza on the southern edge of the Tarahumara country, across the Río Verde. Land is communally held in ejidos or comunidades , with Tepehuan holding title separately, or sometimes with mestizos. They live in groups of small named settlements, called rancherías, surrounding pueblos, or small towns that act as social and political centers. Rancherías are small and widely dispersed, consisting of the separate dwellings of four or five families. Houses in the tierra templada are constructed of timber in small clusters on the great mesas. In the tierra caliente they are made of stone-and-mud mortar and are usually located along the streams that lead down into the canyons.
