And then there was the makeshift cave I tried to dig in an emergency. The snow was deep, but too fluffy and unconsolidated to hold a roof, so a tarp had to do. Not as warm as it could have been, but barely adequate.
If you have time, pile up the snow, then wait a few minutes, the moved snow will consolidate enough to shovel out and make a firm roof.
Just like how avalanche debris or the snowplow berm sets up after moving.
