Waterton-Glacier Internatinal Peace Park, which comprises Glacier National Park in northwestern Montana on the United States side and Waterton National Park in Alberta on the Canadian side, was designated by law as the world's first International Peace Park in 1932. The park is traversed by the Lewis Range and contains outstanding glacial lakes and alpine scenery and is significant as a habitat exceptionally rich in plant and mammal life.
Glacier National Park, Montana has mountain peaks exceeding 10,000 feet and this site includes nearly 50 glaciers, many lakes and streams. The two parks sustain exceptionally diverse and productive habitat, reflected by the natural populations of large mammals and carnivores, including wolves, bears and mountain lions. Glacier National Park is the only location in the 48 contiguous states where these three major predator populations still occur naturally. The park has a wide variety of wild flowers and wildlife, including bighorn sheep and bald eagles. The area has been designated a Biosphere Reserve. The park met the following criteria for inclusion as a World heritage Site: it is an outstanding example of significant geological processes, and it contains superlative natural phenomena, formations, and areas of exceptional natural beauty.
Waterton-Glacier International Peace Park protects an important biological crossroads at the point where the Rocky Mountains reach their narrowest width. The park straddles the frontiers of two nations: the United States and Canada and serves as a reminder that our natural resources have no boundries. It is also a celebration of the longest undefended contiguous border between two nations. (Inscribed in 1995)
