America the Beautiful: Wild Frontier

At America's center, Three Rivers Wild - the Mississippi, the Missouri and the Ohio - combine their strength and transform into a behemoth that splits the nation. Thousands of snow geese arrive with winter, and river otters hunt within breaks in the ice.

East meets Wild West in The Badlands of South Dakota. Famous frontier towns, Crazy Horse, and U.S. Presidents are immortalized here, but living legends thrive just over the hills.

The northern Land of Lakes is a lush realm of forests and wet bogs - but in winter, it's governed by snow and ice. Timber wolves search widely with their powerful noses, while great greys- the largest owls in North America -plunge deep into the snow for a meal.

Down on the Farm, people and animals in America's heartland face a life fraught with risk and danger. In order to share the abundant ecosystem with farmers and their tools, it's safest for wildlife on the fringes: in the field, above the hayloft, and hidden under plow.

The Great Valley was home to some of America's greatest legends. Today, the critters hunted by the likes of Davy Crocket and Daniel Boone still strive in this little-known strip of wilderness.
