Located in the Brabazon Range of southeastern Alaska, Yakutat Glacier is one of the fastest-retreating glaciers in the world. It is the primary outlet for the 810-square-kilometer (310-square-mile) Yakutat Ice Field, which drains into Harlequin Lake and, ultimately, the Gulf of Alaska. Comparing satellite images from 1987 and 2013 show how quickly Yakutat is melting away.
