These photographs capture the retreat of glaciers in one of America's most beautiful national parks.
After 100 years of climate change, only 25 out of the 150 glaciers recorded at the Glacier National Park in Montana still exist.
As these pictures show, places where the ice was once many metres thick have been replaced with sediment, pastures and lakes.
美国冰川国家公园位于美国蒙大拿州北部、与加拿大相毗连的国境线上，是北美特有物种的大观园。
冰川国家公园位于美国蒙大拿州北部、与加拿大相毗连的国境线上。落基山脉从北到南贯穿公园中心。公园占地41万公顷，原是布莱福特部族的印第安保留地的一部分，1910年辟为国家公园。因这里有
美国冰川国家公园(5张)50余条冰川，故得名冰川国家公园。冰川是由降落在高山的大量积雪在重力作用下凝为沿地面运动的巨大冰体形成。在冰川国家公园中以布莱福特冰川最大，占地约4.8平方公里，位于海拔2440米的杰克逊山和布莱福特山北坡。哈里森冰川和庞普里冰川覆盖在南坡，这里也以其美如画卷的山峰闻名。公园北部3000多米高的克利夫兰山为最高峰，园中超过3000米的还有金特拉峰、西耶山和斯廷森峰等。冰川国家公园是北美特有物种的大观园，有一千多种树木花草。在比较干燥的东部山坡上，恩氏云杉、亚高山冷杉、小干松、花旗松和大枝松苍劲挺拔。在气候较暖、比较湿润的西部山坡上，落叶松、冷杉、云杉茂密葱茏。冰川公园里动物种类也很多，有大角山羊、美洲豹、山狗、山猫、驼鹿、美洲大角鹿、黑熊、灰熊、白尾鹿等等。
Even further down: A man stands at Grinnell glacier overlook, observing the large glacier that fills the basin at Lewis mountain range in the Rocky Mountains in 1920, left. Right, by 2008 a man looks down from the same spot and can see lakes and sediment there were previously hidden beneath metres of ice
Awe-inspiring: The Grinnell glacier fills the basin at Lewis mountain range in the Rocky Mountains in 1900
Shrunken: The Grinnell glacier had greatly receded by 2008
Icy: A third view of the Grinnell glacier showing how it filled the basin of the Lewis mountain range in 1900
Going: By 2010 it had receded to reveal the great swathes of sediment beneath
Once mighty: The large Chaney glacier stretches far at Glacier National Park in 1911
No longer: By 2005, when this picture was taken, the glacier has shrunk dramatically
Deep freeze: A large Iceberg Glacier located at Glacier National Park in 1940
Since thawed: That glacier as photographed by researchers in 2008
You wouldn't get far on skis: The Logan glacier stretches far at Glacier National Park in 1914, left. Right, the same glacier had nearly disappeared by 2009
Snowy peaks: The Blackfoot glacier and Jackson glacier join together at Glacier National Park in 1914
Now just a sprinkle: The Blackfoot glacier and Jackson glacier have greatly receded and are no longer connected
Ice age: The Sperry glacier fills the basin in Glacier National Park in 1913
Heating up: The glacier has shrunk greatly and only patches remain
Chilled: The Harrison glacier, the largest in the park, spreads out across the Rockies
Global warming: The glacier is still the park's largest, but its disappearance now leaves massive sections of mountain visible
