Build an Igloo: Emergency Shelter Guide

Finding yourself in a cold-weather emergency situation demands quick thinking and resourcefulness. While modern survival gear is invaluable, knowing how to construct a basic shelter from the environment can be life-saving. One of the most iconic and effective emergency shelters is the igloo. Traditionally built by the Inuit, an igloo isn't just a fascinating feat of engineering; it's a surprisingly warm and protective structure when constructed correctly. This guide will walk you through the process of building an igloo for emergency shelter, covering everything from site selection to finishing touches.

It’s crucial to understand that building a successful igloo requires specific snow conditions and a significant time commitment. This isn’t a quick fix, but a substantial undertaking. Before attempting to build an igloo, assess your situation and consider if other, faster shelter options – like a snow trench or lean-to – might be more appropriate given your time and energy levels.

Understanding the Right Snow

Not all snow is created equal when it comes to igloo construction. You need sastrugi – wind-packed snow that’s dense and cohesive. This type of snow is typically found in areas exposed to consistent winds. The blocks need to be strong enough to support their own weight and the structure as a whole. If the snow is too powdery, it won’t hold together. If it’s too icy, it will be difficult to cut and shape. A good test is to try and pack a snowball; if it holds its shape firmly, you likely have suitable snow.

Tools You'll Need

While traditionally built with simple tools, having the right equipment can significantly ease the process. Here’s a list of essentials:

• Snow Saw: A long, sturdy saw is crucial for cutting blocks.
• Knife: For trimming and shaping blocks.
• Shovel: For clearing the building site and moving snow.
• Measuring Stick: To ensure consistent block sizes.
• Gloves: Waterproof and insulated gloves are essential to protect your hands.

Step-by-Step Igloo Construction

1. Site Selection and Preparation

Choose a relatively flat, sheltered location. Avoid areas prone to avalanches. Clear the site of any loose snow or debris. Mark out a circle on the snow – the diameter will determine the size of your igloo. A diameter of around 10-12 feet is a good size for a couple of people.

2. Cutting the Blocks

Cut blocks of snow from the area *outside* the marked circle. Blocks should be rectangular, approximately 3 feet long, 1.5 feet wide, and 1 foot thick. The size can be adjusted based on the snow’s consistency and your strength. Cut the blocks carefully, ensuring they are as uniform as possible. Consistency is key to a stable structure.

3. Building the First Course

Begin laying the blocks around the perimeter of the circle. Angle the blocks slightly inward. This is the foundation of your spiral construction. Each block should lean against the next, creating a stable base. Trim the blocks as needed to ensure a tight fit.

4. The Spiral Construction

This is where the igloo’s unique dome shape begins to emerge. Continue laying blocks in a spiral, gradually angling them more and more inward with each course. Each block rests on the blocks below, and is supported by the blocks around it. This creates a self-supporting structure. You’ll notice the opening getting smaller with each layer.

5. The Keystone Block

The final block, the keystone, is the most challenging to place. It needs to be carefully shaped to fit the remaining opening. It may require significant trimming and maneuvering. Once in place, the keystone locks the entire structure together.

6. Filling the Gaps

Once the structure is complete, fill any gaps between the blocks with loose snow. This will help to insulate the igloo and block out drafts. Pack the snow firmly into the cracks.

7. Creating an Entrance

Dig a small tunnel entrance, preferably facing away from the prevailing wind. This helps to trap warm air inside. You can create a small porch area outside the entrance to further reduce wind exposure. Consider building a small windbreak outside the entrance for added protection. If you're planning a longer stay, you might want to explore shelter options that offer more robust protection.

8. Ventilation

Crucially, create a small ventilation hole near the top of the igloo. This prevents carbon dioxide buildup and ensures a supply of fresh air. A hole about 2-3 inches in diameter is usually sufficient.

Insulating Your Igloo

While snow itself is a good insulator, you can improve the igloo’s thermal performance by adding additional layers of insulation. Pine boughs, animal skins, or even layers of clothing can be used to line the interior walls. This will help to trap more heat and create a more comfortable living space.

Important Safety Considerations

Building an igloo is physically demanding and carries inherent risks. Always work with a partner. Be aware of the potential for hypothermia and exhaustion. Monitor the weather conditions and be prepared to abandon the project if conditions deteriorate. Never enter an igloo without ensuring adequate ventilation. Regularly check the structure for stability, especially after heavy snowfall.

Conclusion

Building an igloo is a challenging but rewarding skill that can provide vital emergency shelter in cold-weather environments. While it requires specific snow conditions and a significant time investment, the resulting structure offers surprisingly effective protection from the elements. Remember to prioritize safety, work with a partner, and assess your situation carefully before attempting to build an igloo. Knowing how to construct this type of shelter can be a valuable asset in a survival situation, offering a safe haven from the harsh realities of winter.

Frequently Asked Questions

• How long does it take to build an igloo?

  The time it takes to build an igloo varies greatly depending on the snow conditions, the size of the igloo, and the experience of the builders. A small, simple igloo can take several hours, while a larger, more complex structure can take a full day or even longer.

• What if the snow isn't ideal for building blocks?

  If the snow isn’t dense enough to form stable blocks, you may need to explore alternative shelter options. A snow trench, a quinzee (a hollowed-out snow pile), or a lean-to constructed from branches and snow can provide adequate protection in less-than-ideal conditions.

• How warm can an igloo actually get?

  An igloo can be surprisingly warm, often reaching temperatures significantly above freezing even when it’s well below zero outside. The snow acts as an insulator, trapping the heat generated by body heat and any supplemental heat sources.

• Is it possible to build an igloo alone?

  While technically possible, building an igloo alone is extremely difficult and not recommended. It’s a physically demanding task, and having a partner provides crucial assistance with cutting, lifting, and placing the blocks. It also enhances safety in case of an accident.

• What should I do if the igloo starts to collapse?

  If you notice any signs of structural instability, such as cracks or sagging blocks, evacuate the igloo immediately. Attempting to reinforce a collapsing structure is dangerous. Assess the situation and either rebuild the igloo in a more stable location or seek alternative shelter.
