Askja Caldera

Askja is a caldera located in a remote part of the central highlands of Iceland. Calderas are large, cauldron-like hollows that form after the magma chamber of a volcano is evacuated and the earth above collapses into it. Askja is roughly 2.8 miles (4.5 km) in diameter and is accessible only a few months out of the year — in fact, the region in which it is located is so remote and otherworldly, it was used as a training site for NASA's Apollo program to prepare astronauts for lunar missions.
