Quick Answer
Short Answer: Alternatives to fire platforms on snow include tarp or plastic sheet shelters, natural windbreaks created with snow or branches, and snow trench shelters. These structures can provide warmth and protection from wind and precipitation. A well-made snow trench shelter can last for several days.
Shelter Options
When snow is abundant, consider building a quinzhee shelter. Start by piling 2-3 feet of snow in a circular shape. Allow it to settle and harden before scraping away the surface layer with a shovel. This creates a hollow space that can be used for warmth and shelter.
Alternative Platforms
For a tarp or plastic sheet shelter, select a spot with a natural windbreak, such as a group of trees or a snowbank. Use rope or twine to secure the tarp or plastic sheet to the ground, anchoring it with rocks or snow anchors. Ensure the structure is sloped to allow snow to slide off, preventing collapse.
Snow Trench Shelters
To build a snow trench shelter, dig a trench 2-3 feet deep and 4-6 feet long. Use a shovel to create a sloping roof, allowing snow to accumulate and provide insulation. Pack the walls with snow to prevent collapse. These shelters can be made in as little as 30 minutes and provide warmth and protection for several days.
