The northwest corner of Montana is big, wild country defined by pristine lakes and rivers, vast forests, and sprawling mountain ranges. The region is part of the Crown of the Continent Ecosystem, which represents one of the most intact ecosystems in the world. The expansive landscape is home to a rich diversity of wildlife and nearly all of North America's large mammals, including grizzly bears, mountain lions, wolves, lynx, deer, elk, moose, bighorn sheep, and mountain goats.
