farther west from Pali-Aike lies the actual Andean volcanic arc in the form of the Austral Volcanic Zone, a chain of stratovolcanoes and one volcanic field (Fueguino) which is South America's southernmost volcano. The 2.9-2.5million years old Camusu Aike volcanic field is northwest and Morro Chico volcano about west of Pali-Aike.
