El Solo Volcano

El Solo is a stratovolcano on the border between Argentina and Chile, west of Ojos del Salado. Lying in the Andes Mountain Range, it consists of nine eruptive centers and is covered in light-colored rhyodacite pyroclastic flow deposits. El Solo is 6190-m-high and was the source of major rhyodacitic pyroclastic-flow deposits erupted during the Holocene that thickly fill adjacent valleys.
