The snow cave

Last weekend I carved the snow cave, see here from inside.
Before starting to work real work inside the house with computer, I made the cave a bit bigger. Now I know in practice how to make such a cave and I have to say that without emergency reason it is not clever to do such for one night. There is enough work and one gets quite wet. Now the cave is from down to top three meters high!
And you see the important equipments outside the cave, which I should use if being in emergency on mountains.
