Mapping lava tubes in the Galàpagos | The Source | Washington University in St. Louis
Yearly expeditions to explore the lava tubes on the famed archipelago will culminate in an international symposium to be held there next year. In the meantime we may all be able to participate as well, if only vicariously. WUSTL's Aaron Addison, who has traveled to the Galàpagos repeatedly to map the tubes, apppears in a new IMAX film called Galàpagos 3D. Not yet released in the United States, it stars David Attenborough as well as the archipelago's fantastic geology and biology.
