Geography[change | change source]

The Aconcagua river through La Calera

The Aconcagua river has a length of 142 km (88 mi), and a drainage basin with an area of approximately 7,340 km2 (2,834 sq mi).[1]

Course[change | change source]

The Aconcagua river starts on the Andes at an elevation of about 1,430 m (4,692 ft), at the confluence of two rivers:[1]

  • Juncal river, that starts in the Nevado Juncal mountain; it is 35 km (22 mi) long.
  • Blanco river, that is 15 km (9 mi) long.

From its start, the river flows through the Aconcagua valley. Before the city of Los Andes, the river is joined, as a right tributary, by the Colorado river, 58 km (36 mi) long, and then, after the city of San Felipe, by the Putaendo river, also a right tributary with a length of 34 km (21 mi).[1]

The river keeps flowing to the west, running through the cities of La Calera and Quillota, in the Quillota province. Finally, the Aconcagua river flows in the Pacific Ocean at the city of Concón, in the Valparaíso province.
