Winter is one of the easiest seasons to follow the movements of wildlife in the national parks. Not only can their every move be captured in the snow, but on rare occasions you can follow the interplay between animals.

One of the "crown jewels" of the national park system will celebrate its centennial in 2010, and when you're talking about planning a celebration of that magnitude, there's plenty of work to do. Glacier National Park is off to a great start in that regard, and you may want to know about upcoming deadlines for some activities that are already underway.

While most often we hear about fish, bird, or animal species needing Endangered Species Act protection, today a group is asking the U.S. Fish and Wildlife Service to extend that protection to a tree, the whitebark pine.

Glacier National Park includes just over a million acres of superlative Rocky Mountain terrain, and the park offers an interesting combination of front-country access and backcountry solitude in what has been called "the core of the Crown of the Continent ecosystem." Glacier will celebrate its centennial on May 11, 2010, and some supporters are saying it's time to finally formalize wilderness designation for key portions of the park.
