Nevado Ojos del Salado ("Source of the Salt river" summit) is a massive stratovolcano in the Andes on the Argentina-Chile border and the highest volcano in the World at 6,893 metres (22,615 ft). It is also the second highest mountain in the Western Hemisphere and Southern Hemisphere and the highest in Chile. It is located about 600 kilometres (370 mi) north of Aconcagua, the highest mountain in the Western Hemisphere at 6,962 m (22,841 ft).
Due to its location near the Atacama desert, the mountain has very dry conditions with snow only remaining on the peak during winter. Despite the generally dry conditions, there is a permanent crater lake about 100 metres (300 ft) in diameter at an elevation of 6,390 m (20,960 ft) on the eastern side of Ojos del Salado. This is most likely the highest lake of any kind in the world.
