The volcanic seven summits include two potentially active, three dormant and two extinct volcanoes.
Ojos del Salado, South America
Nevajo Ojos del Salado is a massive stratovolcano rising in the Andes on the border of Argentina and Chile. At 6,891 meters (22,608 ft) high, it is known as the world’s highest volcano, the second highest mountain in the Western Hemisphere and the highest mountain in Chile. The volcano is situated about 600 km (370 mi) north of Aconcagua, the highest mountain in the Western Hemisphere.
Ojos del Salado is near the Atacama desert, thus, the mountain has very dry conditions with snow only remaining on the peak during winter. A permanent crater lake measuring 100 m (300 ft) in diameter can also be found on the eastern side of the volcano. With an elevation of 6,390 m (20,960 ft), the lake is believed to be the highest in the world.
The name Ojos del Salado means “eyes of the salty mountain,” a name which came from the huge salt deposits that, in the form of lagoons or “eyes,” appear in its glaciers.
It is not known how Kilimanajaro got its name but it is believed to be a combination of the Swahili word Kilima, meaning “mountain,” and the KiChagga word Njaro meaning “whiteness,” giving its other name "White Mountain."
Pico de Orizaba, North America
The name Volcan Pico de Orizaba means “Volcanic Peak of Orizaba,” while its Aztec name Citlaltepetl, means “Star Mountain.”
The name of this snow-covered volcano means “Snowy Mountain,” from the Sanskrit himavant.
