Although the mountain volcano Mauna Kea last erupted around 4,000 years ago, it is still hot today, the center of a burning controversy over whether its summit should be used for astronomical observatories or preserved as a cultural landscape sacred to the Hawaiian people. For five years the documentary production team Nā Maka o ka 'Āina ("the eyes of the land") captured on video the seasonal moods of Mauna Kea's unique 14,000-foot summit, the richly varied ecosystems that extend from sea level to alpine zone, the legends and stories that reveal the mountain's geologic and cultural history, and the political turbulence surrounding the efforts to protect the most significant temple in the islands: the mountain itself.

This astounding documentary delves into the mysteries of the Tunguska event – one of the largest cosmic disasters in the history of civilisation. At 7.15 am, on 30th June 1908, a giant fireball, as bright the sun, exploded in the sky over Tunguska in central Siberia. Its force was equivalent to twenty million tonnes of TNT, and a thousand times greater than that of the atomic bomb dropped on Hiroshima in 1945. An estimated sixty million trees were felled over an area of over two thousand square kilometres - an area over half the size of Rhode Island. If the explosion had occurred over London or Paris, hundreds of thousands of people would have been killed.
