America's Wild Border: Northern Exposure

The frontier between America and Canada is the longest on Earth, spanning 5,525 miles and crossing a wide range of habitats and weather extremes. The animals that call this stretch of land home are equally diverse, from the lynx and red-tailed hawks of Washington and British Columbia to the puffins and lobsters of the Atlantic Ocean's Gray Zone to all the prairie and grassland creatures in between. Take an in-depth look at life in the northern borderlands and see how its many species adapt, survive, and thrive here over the course of a year.
