Just two hours east of Davis in the Sierra Nevada mountains lies the largest alpine lake in North America. The transparent cobalt blue waters of Lake Tahoe are almost as pure as distilled water. However, over the past 50 years the lake has lost about one-third of its clarity. Meet Chris Joseph from Keep Tahoe Blue and learn about the many threats to the blueness of the lake and what we can do to keep it pristine and clear. Explore some of the clearest and bluest lakes around the world from New Zealand to Siberia. Then travel to Lake Tahoe to kayak in Emerald Bay, hike through Desolation Wilderness, meet a fish called Tessie, and help preserve the natural wonder of this sparkling azure Lake of the Sky.
