HERMOSILLO

city, capital of Sonora state, northwestern Mexico. Situated on the coastal plain, at an elevation of 778 ft (237 m) above sea level, near the confluence of the Sonora and San Miguel rivers, it is south of Nogales on the Mexico-U.S. border and east of Kino Bay on the Gulf of California coast. In addition to its administrative functions, Hermosillo is an important commercial and manufacturing centre for the surrounding irrigated farmlands, which yield fruit, wheat, cotton, corn (maize), and beans. Cattle are also raised. Modern buildings contrast with those of Spanish colonial design in Hermosillo. The city houses the University of Sonora (1938) and is also a popular winter resort. Copper is mined nearby. Major highways and railroads linking Mexicali and Nogales with Mexico City pass through Hermosillo, which also has an airport. Pop. (1980) 297,175.
