Located in the northwest corner of Greenland, Leidy Glacier is fed by ice from the Academy Glacier. As Leidy approaches the sea, it is diverted around the tip of an island that separates the Olriks Fjord to the south and Academy Cove to the north. The crisscross pattern is the result of ice flowing along the path of least resistance. Photo: NASA/Terra

Located in the Brabazon Range of southeastern Alaska, Yakutat Glacier is one of the fastest retreating glaciers in the world. Over the past 26 years, the glacier’s terminus has retreated more than 5 kilometres. Apart from the natural change, human-caused global warming has hastened the speed of the retreat.
