BBC America Documentary Nature

Alaska is huge – a fifth of the size of the US – but with fewer than three-quarters of a million human beings. Instead, it has a phenomenal range of wildlife. Why should such a vast land, part of the most modern nation on earth, still be so untamed and barely trodden, yet full of life? It’s because a unique combination of forces made it, and still dominate it. Narrated by Dougray Scott, this three-part BBC Earth series explores spring, summer and winter, discovering the unique species that have learned to thrive in these harsh conditions.
