This transnational natural site encompasses a vast region of mountains, glaciers, and coastal landscapes spanning the border between the United States and Canada in northwestern North America. The property protects an interconnected wilderness system featuring dramatic mountain ranges, extensive ice fields, and pristine fjord environments that represent major ecosystems of the North Pacific coast. The site's geological significance lies in its active glacial processes and the visible evidence of glaciation across multiple landscapes, demonstrating contemporary environmental dynamics in high-altitude alpine and subarctic regions. The area supports diverse wildlife populations adapted to mountainous and coastal habitats, including species of regional and continental importance. The ensemble of interconnected protected areas preserves ecological systems that have remained largely unmodified by human development, offering substantial scientific value for understanding natural processes in northern latitudes. The striking visual character of the region is defined by snow-covered peaks, extensive blue ice fields, and the dramatic meeting of mountains with ocean fjords.
