Sonora, the second largest state in Mexico, is sparsely populated. Mountainous and arid, the region is sunny almost year–round and has little rainfall. Nearly all of Mexico’s copper is produced here. Culturally, Sonora offers a unique blend. Ancient societies–such as the Yaquis, Mayos and Cucapas–remain active in the state. Bordered by Arizona and New Mexico, Sonora is also influenced by American trends and fashions.
