There you see it's just all free-floating, broken ice. 满眼尽是残破的浮冰

Kind of like lots of mini, little icebergs here.But they are gonna be super unstable. 就像众多的小型冰山 但它们非常不稳定

It's only about 100 meters, look, across the main glacier. 宽度大概有一百米  看那边是主冰层

Might have to be a case of being a bit light-footed on it. 踩在上面要很轻

Okay, here we go, twinkle toes.Because it's less dense than water, ice floats. 上吧  一展脚功的时刻到了 冰比水密度小  故能浮于水面

These small bergs should support my weight. 这些小冰块应该能承受我的体重

But there's no way of telling how stable they're gonna be. 但谁也不知道它们的承重能力如何

Just! Okay, give me your hand this last bit.One, two, three. Good. good. And again. Nice. 好险  好了  我来拉你  一  二  三  很好  再来

Sometimes you just got to commit to these things. 有时你就要冒险一搏

Okay, next little bit.You see how undercut all this stuff is. 好了  过来一点 你会看到这些冰块有多薄

You don't know whether what you're standing on is just gonna drop you straight in the drink,or it's gonna be solid. 你不知道接下来要踩的冰块 是会让你掉到水里 还是足够坚固

You do not want to end up freezing cold in this water up here. 没人想掉到冰冷的水中 而被冻得半死

This water will refreeze at night,and by day, it will be only just above zero. 这些水晚上会再度结冰 在白天也是刚刚达到融化的温度

It's like I've crossed a minefield and now I'm onto solid ice. 刚才简直跟穿越雷区一样惊险 而现在我到了坚固的冰面上

Alaska's home to more than half the world's glaciers,over 100,000 of them. 阿拉斯加拥有世界半数以上的冰川 超过十万座

In early summer, when they're melting and moving, 初夏时节  它们会融化并移动

then they're at their most dangerous.It's no place to hang around. 那时它们最危险 生物无处可依附
