California: Life in Death Valley (PBS)

"Nature's Life in Death Valley takes viewers into the simmering cauldron of one of the world's most extreme environments....In Death Valley, things are never quite as they seem. Beneath its parched surface lies one of America's largest aquifer systems....In this ultimate testing ground, the rules are simple -- adapt or perish." -- from the website. <http://www.pbs.org/wnet/nature/deathvalley/>
