National Parks: USA: Season 1, Episode 4

1 - 4: Olympic

Along Washington State's rugged coast, Olympic National Park protects 1 million acres of diverse habitat. Coastal fog hits glacier-capped mountains, drenching the land in record rainfall and giving rise to temperate rainforests. This unique landscape hosts a rich biodiversity, including the endemic Olympic Marmot, Roosevelt elk, bobcats and one of the last Pacific salmon runs in the lower 48.
