Copper Mountain and the surrounding high-altitude drainage systems of the North Cascades define this landscape along the international boundary. The terrain is characterized by steep elevation changes and a network of glacial-fed waters, including the Little Chilliwack River and the principal Chilliwack River. This area serves as a critical point of cross-border topography where the United States and British Columbia meet.
