Galapagos

Born of Fire (1x1)

Air date: Sep 29, 2006

Many of the Galapagos' volcanoes that brought about its existence remain active, and there's amazing footage of an eruption of the Sierra Negra. Marine iguanas leap off lava cliffs into billowing surf; giant tortoises are groomed by Darwin's finches; and the waved alabatross shows off with a magical courship display.
