00:02.270 --> 00:05.573
- [Narrator] This is a snow cave made for six persons.

00:06.030 --> 00:07.763
Dig in here so we can stand.

00:08.570 --> 00:09.800
And then make this level

00:11.260 --> 00:13.540
and we have the roof over us.

00:13.540 --> 00:16.713
We have to have one and a half feet of snow at least.

00:16.832 --> 00:19.249
(soft music)

00:20.821 --> 00:22.160
- [Man Shoveling Outside] But surely outer layer here

00:22.160 --> 00:26.623
I think will be faster or quicker to do with the shovel.

00:26.623 --> 00:29.040
(soft music)

00:34.635 --> 00:38.823
- [Worker] In here is always about zero Celsius degrees,

00:39.020 --> 00:41.033
no matter what the weather outside is.

00:41.350 --> 00:43.123
So it's quite comfortable.

00:43.370 --> 00:47.333
It takes us about four to five hours to dig it out.

00:47.670 --> 00:51.163
And once it's done, it can stand for many days.

00:52.470 --> 00:53.303
We can use it.

00:53.825 --> 00:56.242
