Mastering The Underground World (Episode #103H)

KQED 9: Wed, Jul 30, 2014 -- 11:00 PM

It's a whole new world down there if we can conquer its challenges. Some of the greatest human minds have been engaged in making the underground safe and accessible. In this program we look at the most breathtaking feats of technology, past and present. From pick-axed tunnels to an excavated mountain, from Roman sewers to a vast 27km long particle accelerator - these are the ways we've harnessed the potential of this, the planet's last frontier.

Secrets & Treasures (Episode #102H)

KQED 9: Wed, Jul 23, 2014 -- 11:00 PM

The underground world is one of secrets, ideal for hiding everything from misdeeds to the world's greatest works of art. This program reveals some of the most exciting discoveries of buried treasure - then takes us to another kind of secret, the sort that governments like to hide, not just from their enemies, but from their own people. From ancient history right up to the present day, the underground world is the first choice for those seeking concealment.

Natural Wonders (Episode #101H)

KQED 9: Wed, Jul 16, 2014 -- 11:00 PM

Much of the underground world is carved by nature; many of its greatest treasures are the result of elemental processes as old as the planet itself. We haven't been slow to make use of these extraordinary and dramatic spaces - they provide us with a record of our earliest history, if we know where to look. But it's a dangerous, often threatening realm, with its dark caverns, narrow environments and rushing water. Far from the light of day we join intrepid underground explorers as they push back the boundaries, make amazing discoveries and share sights of remarkable beauty.
