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. north of Valparaiso. The river has a course of about 200 m., and its waters irrigate the most populous part of the Chilean province of Aconcagua the same name.
The Cerro Aconcagua is located in Argentina and is the highest mountain in The Americas and the Southern Hemisphere, as well the highest peak outside of Asia and one of the Seven Summits.
The AconcaguaRiver rises on the southern slope and flows west, meeting the Pacific Ocean 20 km north of ValparaÃso, Chile.
In mountaineering terms, Aconcagua is technically an easy mountain if approached from the North, the 'Normal route', on this approach no actual climbing is needed although the effects of altitude are severe (atmospheric pressure is 40% of sea-level at the summit).
From the superior course of the Aconcaguariver to inferior course the vegetation is diverse.
The regional hydrography is constituted by the hydrographic hole of the AconcaguaRiver and its tributary ones, that covers a surface of 7,640 Km2 (46.6% of the regional surface).
The Aconcaguariver is born in the Mountain range of The Andes, in the confluence of the rivers Juncal and Blanco.
