Can you build an igloo for emergency shelter?

Planning and Materials

When planning to build an igloo for emergency shelter, it’s crucial to have the right materials and a basic understanding of the process. You’ll need snow that’s at least 4-6 inches deep and has the right consistency to hold your weight and the weight of the structure. Ideally, the snow should be powdery and not too wet, as this will make it easier to cut and shape. You’ll also need a shovel, a saw or a knife, and a block of snow that you can use as a base or " anchor" to start building your igloo.

Building Techniques

To build an igloo, start by creating a foundation that’s about 6 feet in diameter and 2 feet high. Place your anchor block in the center and begin cutting blocks of snow from the surrounding area, using your shovel or saw to shape them into the right size and shape. Place each block on top of the previous one, overlapping them slightly to create a strong bond. As you build, make sure to create an arch shape for the dome of the igloo, using a consistent pattern to maintain structural integrity. Continue building in layers, each one slightly smaller than the last, until you reach the desired height. A good rule of thumb is to aim for a height of about 6-8 feet, which will provide enough space for a small shelter.

Safety Considerations

When building an igloo in arctic weather conditions, safety should be your top priority. Make sure to build in a location that’s protected from wind and extreme cold, and take regular breaks to avoid exhaustion and frostbite. Also, be aware of the risks of avalanches and crevasses in areas with steep slopes or uneven terrain. Finally, always test the structural integrity of your igloo before entering it, making sure that it’s stable and can support your weight. With the right materials and a basic understanding of building techniques, you can create a safe and effective emergency shelter in the form of an igloo.
