Nevados Ojos del Salado is the world's highest active volcano. It is located on the Chile/Argentina border.
It is located about 20 km south of the road that crosses the international border at Paso de San Francisco. The mountain has very dry conditions with snow only remaining on the peak during winter. The volcano contains two summit peaks of the same height.
A large explosive eruption occurred about 1000-1500 years ago, producing pumiceous pyroclastic flows.
There are no confirmed historical eruptions of Ojos del Salado. There was an unconfirmed report of minor gas-and-ash emission in 1993. The volcano currently shows fumarolic activity.
