I'm very sorry for the bad pictures of this snow architecture, but I just had to post these because this is the coolest house! It had different rooms and it even had different levels with stairs built in the snow. A man and his kids were sleeping in it the night I saw it. My friend told me that a hut like this is called a quonset.
This was up by Flat Top in the eastern range of mountains in Anchorage, AK.
