Glacier National Park is located in northwest Montana, on the Canada–United States border with the Canadian provinces of Alberta and British Columbia. The park encompasses over 1 million acres (4,000 km2) and includes parts of two mountain ranges, over 130 named lakes, more than 1,200 different species of plants, 700+ miles of trails, over 270 species of birds, and nearly 70 species of mammals. This vast pristine ecosystem is the centerpiece of what has been referred to as the “Crown of the Continent Ecosystem”, a region of protected land encompassing 16,000 square miles (41,000 km2).
