Snow huts, also known as igloos, are temporary shelters made of snow and ice blocks. They are traditionally used by the Inuit people of the Arctic regions as a form of protection from the cold and windy weather. Igloos are constructed in a dome shape and are usually built with a single entrance. The walls of an igloo are made of blocks of snow that are packed together tightly to create a strong and insulated structure. Inside, the igloo is usually lined with fur or other materials to provide additional warmth.
