From the Amazon to the Arctic

Embark on thrilling journeys of discovery in which ancient ways of life are preserved, and passed on to a new generation. In Alaska, the last great American frontier, two old friends embark by dogsled on a mission to document a remote Native-American village before it becomes a ghost town. In Ecuador, join a father and his family as they venture down the mighty Amazon River and into the rainforest to learn such secrets of survival as how to use plants to construct a shelter and cure ailments. In the Caribbean, join a crew on the maiden voyage of a vintage two-masted brigantine, and get a glimpse into the life of whalers who battled behemoths from tiny wooden boats. In Colorado, explore towering cliff dwellings, as beautiful as they are baffling, and that hold the secrets of a vanished civilization, the Anasazi Indians.
