HOW TO MAKE A SNOW CAVE
A snow cave is a great type of snow
shelter if the conditions are right for one. You need to find
a deep snow drift, be aware that the reason there's a snow
drift where there is one is because a large amount of snow
gets deposited there, usually
by a big boulder. You need to put your
entrance in a place where it won't get
covered in snow
during the night in
case of snow
and wind.
If you're digging your cave by a large rock start digging
the entrance facing as far away from the direction of the snow
accumulation as possible. The entrance hole to your snow
cave should be as low down as possible.

Dig in, and then up. There should be a floor area in your
snow cave that is lower than the sleeping areas but higher up
than the entrance hole. The sleeping areas should be higher up
to take advantage of the warmer air closer to the ceiling.
Trim the inside walls and ceiling smooth to prevent water
dripping. And most importantly, poke a ventilation hole in the
ceiling with a ski pole or a stick and leave it in there so
you can wiggle it once in a while to keep it clear. Without a
ventilation hole you could die in your sleep so make sure you
have one. Cover the door with a snow block or a backpack at
night.
