Igloos have served those who live in cold weather for centuries.

In a cold weather survival situation, they can provide life saving shelter, particularly if you are dressed appropriately for cold weather.

Faced with a cold weather survival situation, you must be able to secure yourself shelter.

One way is to build an igloo – with a little work, if the snow is the right type, igloos can provide a shelter that will warm up by about 30 degrees Fahrenheit, allowing you to survive alone all but the most extreme cold.

Have you ever built an igloo and stayed overnight in it? How was it? Tell us below.
