（单词翻译）
A snow hole like this will keep you out of the wind. The next thing I need do is to dig a bit of a pit down. And the reason I do that is that cold air sinks. So I don’t want this cold air around me. So I want it to go down into what they call a cold well down here.
What I want to do now is just block up a bit of this entrance here. It’s
tempting1 to seal the entrance completely to keep the wind out. But that can be
lethal2. Ok, what I’ve done here is just put some of the blocks over the top. And this will
consolidate3 down, left a bit of a ventilation hole. I can put my hand out here. And it’s blowing hard. It’s snowing. I need to give it a light covering. But I need to make sure to keep putting my hands through, keep that ventilation hole. Otherwise, you can
suffocate4 in these things.
Staying hydrated helps keep your body warm. It’s tempting to eat the snow. But that would just cool my core body temperature down even more. So what you need to do is melt the snow with your body heat. As soon as you see a break in the weather, you need to get off the
glacier5 fast. You don’t want to be caught in another storm up here.
It’s definitely less windy than it was yesterday. It’s still pretty windy. But actually, I see the sun over there which is a good sign. You’ll need to find your way and you can use the sun. But in Iceland, the sun doesn’t rise in the east and set in the west. It’s more like southeast and southwest. So that’s southeast now. The sun’s just come out. It means southwest is over there.
Glaciers6 are full of these ice gullies. And they can be dangerous. All of this snow here, uh, this is what’s called rotten snow, which means it’s fallen, it’s
thawed7 and then it’s refrozen. So you get this like crust. It’s really good for walking on. I can just dig my feet in, and get really good holds in it. But the danger on glaciers are
crevasses8.
