Tehua

The plains east of Casas Grandes form part of the dry basin country of northern Chihuahua. Spanish missionaries established a mission at Casas Grandes, while the nearby Janos settlement had a mission of its own. By the 1680s Suma people were reported living with the Janos there. Following the upheavals of 1684–85, Spanish authorities established the presidio of San Felipe y Santiago at Janos.
