Cuyo is the name given to the wine-producing, mountainous area of central-west Argentina. Historically it comprised the provinces of San Juan, San Luis and Mendoza. The term New Cuyo is a modern one, which indicates both Cuyo proper and the province of La Rioja. New Cuyo is a political and economic macroregion, but culturally La Rioja is part of the North-West rather than Cuyo.
Cuyo has some of the most popular tourist attractions in Argentina and the highest mountain massifs in the Andes, including Aconcagua itself, the highest peak outside Asia, and the Ischigualasto Provincial Park.
The soil is arid and reddish, crossed by few rivers. Most of the rivers are fed by the thawing of snow on the peaks, and their volume of water increases considerably in spring. The Desaguadero River is the main collector, receiving waters from the Bermejo, Vinchina and Salado before reaching the Colorado River.
Viticulture is one of the main activities of the area. The wine production of the region represents almost 80% of national production, and the wines are highly considered in the world. Olives, potatoes, tomatoes and some fruits are also cultivated, and there is production of sweets and preserved foodstuffs. Quarrying and oil exploitation are other important industries.
The Province of Mendoza (Spanish pronunciation: [menˈdosa]) is a province of Argentina, located in the western central part of the country in the Cuyo region. It borders to the north with San Juan, the south with La Pampa and Neuquén, the east with San Luis, and to the west with the republic of Chile; the international limit is marked by the Andes mountain range. Its capital city is the homonymous city of Mendoza.
Covering an area of 148.827 km², it is the seventh biggest province of Argentina with 5.35% of the country's total surface. The population for 2010 is 1.741.610 inhabitants, which makes it the fourth largest populated province of the country, or 4.35% of the total national population.
