Guanajuato, officially Free and Sovereign State of Guanajuato is one of the 31 states which, with the Federal District, are the 32 Federal entities of Mexico. It is divided into 46 municipalities and its capital city is Guanajuato. The largest city in the state is León.
It is located in North-Central Mexico. It is bordered by the states of Jalisco to the west, Zacatecas to the northwest, San Luis Potosí to the north, Querétaro to the east and Michoacán to the south. It covers an area of 30,608 km2 (11,818 sq mi).
Guanajuato is located between the arid north of the country and the lusher south, and it is geographically part of the Trans-Mexican Volcanic Belt, the Mexican Plateau and the Sierra Madre Oriental. It was initially settled by the Spanish in the 1520s due to mineral deposits found around the now capital city of Guanajuato, but areas such as the Bajío region also became important for agriculture and livestock. Mining and agriculture have been the traditional mainstays of the state's economy, but today, about 30% of the state's GDP is accounted for by industry, which includes metals, automobiles, leather goods, processed foods and more.
The state is home to several historically important cities, especially those along the "Bicentennial Route", which retraces the path of Miguel Hidalgo y Costilla's insurgent army at the very beginning of the Mexican War of Independence. This route begins at Dolores Hidalgo, and passes though the Sanctuary of Atotonilco, San Miguel de Allende, Celaya and the capital of Guanajuato. Other important cities in the state include León, the most populous, and Irapuato.
Guanajuato is located in the center of Mexico, north-west of Mexico City, bordering the states of Zacatecas, San Luis Potosí, Michoacán, Querétaro and Jalisco. It covers an area of 30,589 km² and is ranked 20th out of 31 states. It has an average altitude of 2,015 meters (6,611 ft) above sea level, with its territory divided among three of Mexico's physical regions, the Sierra Madre Oriental, the Mexican Plateau and the Trans-Mexican Volcanic Belt. The Sierra Madre Oriental in Guanajuato consists of the Sierra Gorda and the Sierra del Azafrán in the northeast. The Mexican Plateau extends through the center of the state. Within, it subdivides into various regions parted by low-lying mountain chains such as the Sierra de la Cuatralba and the Sierra de Cubo. The Trans Mexican Volcanic Belt crosses the state in the south and includes the Bajío area, the Altos de Jalisco and the valleys area in the far south. The state is crossed by several mountain ranges which have mountains between 2,300 and 3,000 meters high. Mountain ranges average 2,305 meters and flat areas lie at around 1,725 meters above mean sea level. The other important mountain ranges include the Sierra Gorda to the north, the Sierra de Guanjuato in the southeast, the Comanja in the northwest and the Codorniz in the east.
The state is divided into five regions, taking into consideration geography and climate. These are called Altos de Guanajuato, La Sierra Central, Bajío, La Sierra Gorda and Los Valles del Sur. The Altos de Guanajuato, located in the north of the state, are a chain of forested mountains interspersed with pastures, small fields and areas with cacti and other desert plants. They begin near the border with San Luis Potosí, and extend south to Dolores Hidalgo and then to San Miguel de Allende, then to the Querétaro border. The altitude of this area varies from 1,800 to peaks over 2,900 meters such as the La Giganta and La Sierra del Cubo mountains. The climate is mostly semiarid with a rainy season in the summer, with average temperatures between 15 and 20 °C. However, lows in the winter frequently reach 0 °C or lower with frosts. Wildlife is found mostly in the most rugged and inaccessible areas and includes deer, coyotes, eagles and rattlesnakes.
