Llullaillaco is a dormant stratovolcano on the border between Argentina and Chile. It lies in the Puna de Atacama, a region of tall volcanic peaks on a high plateau close to the Atacama Desert, one of the driest places in the world. Its maximum elevation is most commonly given as 6,723 metres (22,057 ft), making it the second- or third-highest volcano in the world. Between 3700 m and 5000 m elevation there is a sparse plant cover, while at lower altitudes the climate is too dry for plants to grow. The volcano formed during the Pleistocene in two stages. The oldest rocks are about 1.5 million years old. About 150,000 years ago, the volcano's southeastern flank collapsed, generating a debris avalanche that reached as far as 25 kilometres (16 mi) from the summit. There are reports of activity from the 19th century. There are a number of archaeological sites on the mountain; Llullaillaco marks the highest archaeological site in the world. (Full article...)

Why you should extend your general knowledge:
There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.
As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
