Quick Answer
When building an emergency shelter in snow, use a quinzhee or a snow trench as the foundation, and then create a windbreak using snow or a reflective blanket to reduce heat loss. Add a sleeping platform and insulation to maintain body heat. This simple shelter can be built within an hour.
Building a Quinzhee Shelter
A quinzhee is a simple snow shelter that can be built using a shovel and a slope with deep snow. Start by scraping away the surface snow to reveal the underlying drift. Then, shovel the snow into a pile, creating a quinzhee shape. Pack the snow down to create a solid base, and use your body weight to compact the snow into a solid wall. Add a windbreak and a sleeping platform to complete the shelter.
Snow Trench Shelter
A snow trench shelter is another option for building a shelter in snow. Dig a trench that is about 6-8 feet long and 2-3 feet wide, and then shovel the snow into a slope on either side. Add a windbreak and a sleeping platform to the trench, and use insulation to maintain body heat. A snow trench shelter can be built using a shovel and a small amount of snow.
Windbreak and Insulation
A windbreak is essential for reducing heat loss in a snow shelter. Use a reflective blanket or a piece of plastic to create a windbreak, and add insulation to maintain body heat. You can use dry leaves, grass, or even your own clothing to insulate the shelter. Add a sleeping platform to the shelter using a bed of snow or a piece of bark, and use a tarp or a plastic bag to cover the platform and keep it dry.
