BBC Earth has just recently released Yellowstone: Battle For Life, yet another reference-quality nature documentary. This one is about the first National Park, which is still one of the most lovely to visit. The 2.5 hour doc follows the wildlife of Yellowstone surviving through the seasons and highlights the stunning beauty of the park itself. I hope the fact they didn't put the bears, wolves, and bison on the cover doesn't mean people will pass it up on the video store shelf, because it's every bit as good as the Planet Earth series. There's plenty of flora and fauna on display, and for those who've never been, a view of just how biodiverse one National Park can be.

The 1080i video track and DTS-HD Master Audio track will greatly exceed the quality of presentation available on a HD cable provider. No, you didn't read that wrong, this is a 1080i transfer rather than 1080p (probably in the interest of squeezing it onto one disc). Trust me, it still looks great. There's a "People of Yellowstone" featurette included as well. Yellowstone: Battle For Life hit the street back on 9.29. Amazon has the Blu-ray for $17.49. It's also available on DVD, but if you're buying it, you want it in hi-def.
