Volcán San José on the far left horizon rises to the north above ice pinnacles at the Nieves Negras pass on the Chile/Argentina border. The summit (5856 m) of San José is formed by a cluster of six Holocene craters, pyroclastic cones, and blocky lava flows that lie within a series of elongated, 0.5 x 2 km wide nested craters.
Mild phreatomagmatic eruptions were recorded at San José in the 19th and 20th centuries.
Its last eruption was in 1960.
