These parks com­prise an impres­sive com­plex of glac­i­ers and high peaks on both sides of the bor­der between Cana­da (Yukon Ter­ri­to­ry and British Colum­bia) and the Unit­ed States (Alas­ka). The spec­tac­u­lar nat­ur­al land­scapes are home to many griz­zly bears, cari­bou and Dall‘s sheep. The site con­tains the largest non-polar ice­field in the world.
