Alaska: Ancient Rainforest
The Tongass, the largest protected forest in the United States, is also the closest rainforest to the Arctic circle. But how can a forest thrive in a region once dominated by glaciers? The secret lies in warm ocean water, which creates a temperature mild enough to sustain the dense forest growth. In addition, nearly 17 feet of annual rainfall drench this area the size of West Virginia, creating majestic biodiversity that includes 5 species of salmon, the largest population of bald eagles in the world, and over 30,000 bears.
