ACONCAGUA RIVER

Spanish Ro Aconcagua river in central Chile. It rises in the northwestern foothills of Mount Aconcagua of the Andes Mountains and flows westward from the Argentine border area through Valparaso regin to enter the Pacific Ocean north of the city of Via del Mar after a course of 120 miles (190 km). Much of the Chilean trackage of the former Transandine Railway to Mendoza, Argentina, followed the river valley.
