On December 6th, 1995, UNESCO designated the Waterton-Glacier International Peace Park as a World Heritage Site.
  Originally, the International Peace Park commemorated the peace and goodwill that exists along the world's longest undefended border (8,892 km/ 5,525 miles). Today, the united parks represent the need for cooperation and stewardship in a world of shared resources. Cooperation within the Peace Park is reflected in wildlife and vegetation management and in search and rescue programs. The parks also share interpretive efforts including joint hikes, programs and exhibits.
