Add article description

Nevado Anallajsi is a stratovolcano in Bolivia. The date of its last eruption is unknown, but its youngest lava flows appear to have erupted from a vent on the north flank of the mountain. The main composition of the volcano is andesitic and dacitic. It overlies a plateau which is composed of ignimbrite. The volcano covers an area of 368.8 square kilometres (142.4 sq mi) and is 10.2 mya old based on its erosion state,[1] while other estimates indicate an age of 2.6 mya.[2]
