The concept of a peace park is one that goes back more than seventy-five years with the creation of the Waterton-Glacier International Peace Park at the border between Montana and Alberta. The park was originally viewed as a symbol of friendship and goodwill but over the years has become an example of a successful transboundary wilderness park. The park thrives due to high levels of cooperation and collaboration between all stakeholders involved, including those involved in the Crown Managers Partnership. The park has survived amidst threats to its sovereignty. The biggest challenge the park and its managers have faced is the growing legislation surrounding border security after the terrorist attacks of 9/11. Since then, the managers of both parks have strived to maintain a permeable border which allows for visitors to enjoy both sides of the park.
