Doug's Geology Journal

A Whole Lotta Lava (1x1)

:

A volcano is going off in Iceland, and Doug gets there fast. The volcano's lava contains rare material from the beginning of Earth's 4.5-billion-year history. Iceland is defined by its geology, and Doug relishes giant waterfalls roaring over ancient lava flows; ice caps, icebergs, glaciers, and geysers; and how the island is split down the middle by the parting of two massive tectonic plates.
