'The Crown of the Continent'

With one million acres of rugged, northwestern Montana wilderness to explore, a trip to Glacier National Park could fill up an entire summer and more. But let's just take one day and virtually visit Grinnell Lake. A 7-mile loop trail, a relatively easy one in this rugged country, takes you to the shores of the lake turned emerald-green by glacial silt. Grinnell Lake—as well as Mount Grinnell and Grinnell Glacier—is named for the naturalist and Audubon Society founder George Bird Grinnell. For two decades, he lobbied for the creation of the park, and on May 11, 1910, the 'Crown of the Continent,' as Grinnell dubbed this area, became the nation's 10th national park.

“大陆之冠”

有一百万英亩崎岖不平的蒙大拿州西北部荒野可供探索，一次冰川国家公园之旅可能会填满整个夏天，甚至更多。但让我们花一天时间去参观格林内尔湖吧。在这个崎岖的国家，一条7英里长的环形小径相对容易，它会带你到达湖岸，湖岸被冰川淤泥染成翠绿。格林内尔湖以及格林内尔山和格林内尔冰川是以博物学家和奥杜邦协会创始人乔治·伯德·格林内尔命名的。二十年来，他一直在游说建立这个国家公园，1910年5月11日，格林内尔称之为“欧洲大陆之冠”的这个地区成为美国第十个国家公园。

The persistence of Perito Moreno

Yes, it's true that glaciers are shrinking, but not all of them. Perito Moreno, a low-lying glacier in southern Argentina, accumulates ice at about the same rate that it melts into chilly Argentino Lake. This equilibrium makes it one of the few glaciers worldwide that aren't losing mass to climate change.

Perito Moreno is an Argentine icon, partly for its unusual accessibility via the lake, the largest within the nation. Visitors to Los Glaciares National Park can boat or kayak out on ice-blue water for a better look—but they need to keep a safe distance as icebergs constantly calve from the glacier's face, creating huge splashes and waves.

佩里托·莫雷诺的坚持

是的，冰川确实在缩小，但不是全部。阿根廷南部的一座低洼冰川佩里托莫雷诺（Perito Moreno）积冰的速度与它融化到寒冷的阿根廷湖的速度差不多。这种平衡使它成为全球为数不多的不会因气候变化而失去质量的冰川之一。

佩里托·莫雷诺是阿根廷的一个标志，部分原因是它通过这个国家最大的湖泊不同寻常的可达性。到洛斯冰川国家公园的游客可以在冰蓝色的水面上划船或皮划艇，以获得更好的观赏效果，但他们需要保持安全距离，因为冰山不断地从冰川表面脱落，形成巨大的水花和海浪。
