The Wife and I in the Snow Shelter
We dug this snow shelter for practice one year, having slept in a similar shelter once before in the Adirondacks I can attest to their value as protection from the elements but they are labor intensive. Don't work up a sweat while making a snow shelter.
Bright colored Frisbees make good shovels for making snow shelters, they pack flat and can double as a plate at dinner time. You might even want to throw it around if you get stir crazy.
