Rio Arriba means "upper river," the Spanish designation for the region of the upper Rio Grande in New Mexico. The county was one of the seven original partidios under Spanish rule. Tierra Amarilla, the county seat, is near popular recreation areas. Much of the Jicarilla Apache Reservation is in Rio Arriba as well as San Juan and Santa Clara Pueblos. The Brazos, Chama, and Rio Grande rivers are important to the county for farming and recreation.
