ACONCAGUA, a small northern province of central Chile, bounded N.
The province is very mountainous, and is traversed from east to west by the broad valley of the Aconcagua river.
The Aconcagua river rises on the southern slope of the volcano Aconcagua, flows eastward through a broad valley, or bay in the mountains, and enters the Pacific 12 m.
The capital is San Felipe, on the Aconcagua river; it had a population of 11,313 in 1895, and an estimated population of 11,660 in 1902.

Beginning with the province of Aconcagua the coast elevations crystallize into a range of mountains, the Cordillera Maritima, which follows the shore line south to the province of Llanquihue, and is continued still farther south by the mountain range of Chiloe and the islands of the western coast, which are the peaks of a submerged mountain chain.
Lying between this coast range and the Andes is a broad valley, or plain, extending from the Aconcagua river south to the Gulf of Ancud, a distance slightly over 620 m.
The culminating point of the Chilean Andes is Aconcagua, which rises to a height of 23, 0 97 ft.
The rivers of the province of Coquimbo - the Elqui or Coquimbo, Limari and Choapa - exist under less arid conditions, and like those of the province of Aconcagua - the Ligua and Aconcagua - are used to irrigate a much larger area of cultivated territory.
The second most important mining industry in Chile, however, is that of copper, which is found in the provinces of Antofagasta, Atacama, Coquimbo, Aconcagua, Valparaiso, Santiago, O'Higgins, Colchagua, Curico and Talca, but the richest deposits are in the three desert provinces.

While in the west of the Andes, from the latitude of Aconcagua, the central valley of Chile runs without any notable interruption to the south end of the continent, a valley which almost disappears to the north, leaving only some rare inflexions which are considered by Chilean geographers and geologists to be a continuation of the same valley; to the east in Argentina a longitudinal valley, perfectly characterized, runs along the eastern foot of the Cordillera, separating this from the preCordillera, which is parallel to the Cordillera de la Costa of Chile.
Between Aconcagua and Mercedario are the passes of Espinacito (14,803 ft.) and Los Patos or Valle Hermoso (11,736 ft.), chosen by the Argentine General San Martin, when he made his memorable passage across the chain during the War of Independence.
