Quick Answer
Igloos can last through a storm, but their durability depends on proper construction and the severity of the weather. A well-built igloo can withstand winds of up to 50 mph and moderate snowfall. However, strong storms or prolonged exposure may cause structural weaknesses.
Factors Affecting an Igloo’s Durability
An igloo’s stability relies on a few key factors: the quality of the snow, the shape and size of the structure, and the technique used for construction. Snow with a high water content or a temperature above freezing can cause the walls to collapse. A properly constructed igloo should have a dome shape with a diameter of 6-8 feet and a height of 4-6 feet.
Techniques for Building a Storm-Resistant Igloo
To build an igloo that can withstand a storm, use the “block and tackle” method, which involves stacking blocks of snow on top of each other with a rope or stick to help guide the blocks into place. This technique creates a stronger and more stable structure than traditional igloo construction methods. Use a minimum of 12 inches of snow for the blocks, and ensure that the snow is compact and not too powdery.
Tips for Improving an Igloo’s Structural Integrity
To improve the structural integrity of an existing igloo, add additional blocks of snow to the top and sides, and make sure the entrance is small and well-anchored. You can also line the interior with a layer of snow or ice to make the igloo more stable. In extreme weather conditions, consider adding a windbreak or a protective covering to shield the igloo from the elements.
