Night Sky

Glacier National Park and its sister park Waterton Lakes National Park of Canada have been designated an International Dark Sky Park by the International Dark Sky Association (IDA). This is the first IDA designation in the world to cross an international border. The designation requires a long-term commitment to preserving dark skies and requires the parks to meet specific objectives. These include preservation or restoration of outstanding night skies, protection of nocturnal habitat, public enjoyment of the night sky and its heritage, and demonstrating environmental leadership on dark sky issues by communicating the importance of dark skies to the general public and surrounding communities, and by providing an example of what is possible.
