Ojos del Salado (ōˈhōs ħĕl säläˈħō) [key], peak, 22,539 ft (6,870 m) high, on the border between Argentina and Chile, in the Andes. It is the second highest of the Andean peaks. In 1956 a Chilean expedition reported its height to be 23,239 ft (7,083 m), thus making it greater than Aconcagua and therefore the tallest peak in the Western Hemisphere, but this report has been unconfirmed.
