The Ascent of the Volcano explained

The castaways, led by Cyrus Smith, embark on an expedition to climb the mountain and determine whether they are on an island or a continent.

What happens

The castaways, led by Cyrus Smith, embark on an expedition to climb the mountain and determine whether they are on an island or a continent. Using a makeshift lens, Smith starts a fire, and the group ascends through volcanic terrain, encountering wildlife such as tragopans and moufflons. After a challenging climb, they reach the summit at night, and Smith confirms they are on an island as the moon reflects on the surrounding sea.
