Big Island and Maui, the southeastern most islands, are therefore the youngest and geologically ...[Read More]

The Salar is part of the Altiplano platea ...[Read More]

It is the planet’s only volcano known to produce lava made of natrocarbonatite, chemically similar to laundry soap, which hardens and decays almost immediately upon exposure to the atmosphere. It is very rare for natrocarbonatite, a type of igneous roc ...[Read More]
