Echoes from the Ice
Season 12
Episode 3
The two-hundred-foot walls of ice in Glacier Bay overwhelm the senses, but they also surround the most beautiful sights Alaska has to offer -- the Northern Lights, roaming grizzly bears, and humpback whales. The glacier itself is also creating new life -- it has retreated some 70 miles up the bay, wiping the ecological slate clean, allowing new plants and animals to start again from scratch.
